In my intention he deserves ALL the Sub´s...and stupid Prank Channels go crazy with subs...poor humanity. Very good information. I´ve refreshed my English skills , and on top of that, I´m packed with new knowledge. Go on to the next Video on this topic. *btw nice Tattoo *sry for misspelling xD i have to refresh even further ;) have a nice day all :)
It's 12:36am and I have my chem final at 9 tomorrow morning and I'd been flipping through my textbook and noticed IR spectroscopy, which I've never seen before, but which definitely will be on the final...so I'd just like to take this time to thank you for saving me about an hour of trying to understand this just from a textbook. Thanks for saving me time and energy!
couldn't have been explained any better. Perfect. Thanks my man! I feel extremely confident with it right now. It's time to look through all your other spectroscopy videos!
finally , a concise explanation on why graphs show transmission and a reference to the detector - looking for this has been killing me , and yet a 10 minute video explained better than i could find after 20 minutes searching, thanks Professor Dave - you're a real lifesaver !
Thank you so much Professor Dave! I read about this in an MCAT prep book... If we ran a spectroscopy of my understanding, it would have demonstrated 0% absorption. After watching your video I have a much better understanding of how this process works! Thank you again!
I´m a spanish speaker and I didn't understand this theme before a found this video, now I totally understand everything, what a great video you have made, thanks
Just like your other videos, this video is perfect for those who need a deeper explanation on infrared spectroscopy. To be honest I struggle with identifying stretches in an IR spectrum and this video explains that and more. Thank you.
thank you so much for posting tutorials like this! I was really confused when reading my textbook but from this short 10 minutes video, I actually understood because your explanation was 🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒
You know... the more I try to actually understand what the hell is going on in the universe, what's happening with bonds, the more impossible learning becomes. Each question I have about the fundamentals of what I've been taught in science leads to me a different rabbit hole. The prerequisite knowledge to understand what's happening usually involves ignoring the desire to understand what's happening in a class that I have to take before hand. Chemistry is the gateway to quantum chemistry, and quantum chemistry is the gateway to every other interaction between atoms. And yet ironically, the highest level classes I can wrap my head around, are prerequisite knowledge to how the universe works. It's frustrating.
Really well explained. From very basics and in depth. Got me to study IRs of some simple molecules as phenol and acetone and benzoic acid. Thank you. IR is a really very interesting concept
The first three minutes are an incredible summation of the theoretical principles of IR Spec 😮 I really wish I had known this existed when I was learning about it in class 😂
Hey Dave.... You are really on of the best teachers in the world. And. the work you do is just extraordinary..... You're Great...... Your tutorials are really useful.....
This video uses a graph inverse of what scientists here use. Instead of dips we use spikes. Otherwise it shows the same information. I finally figured out how to build molecules this way 2 days before the exam
Parabéns pela aula!!!!! Extremamente didático! Você merece muito sucesso! Congratulations for the class!!! Extremely didactic! You deserve a lot of success!
A carbonyl group is C double bonded to O right? The functional group you identified on the right of the whiteboard is an sp2 C-H, which has a significantly different frequency (3050-3150) than carbonyl (1620-1680), which your drew in the spectra. I'm a little confused why you drew the carbonyl frequency in the spectra but identified it's functional group as a sp2 C-H instead?

I'm a senior in college and I've been watching your videos since sophomore year. You sir are a lifesaver and a gradesaver.
I swear one sentence from this man makes me understand the whole topic better than an hour class.
that was insanely well explained. you deserve every single subscriber.
In my intention he deserves ALL the Sub´s...and stupid Prank Channels go crazy with subs...poor humanity.

*sry for misspelling xD i have to refresh even further ;)
have a nice day all :)
Depending on where you are Scientists may use the opposite. Here we invert it, instead of dips we use peaks. Otherwise it's the same
The question is, does he deserve tenure? Perhaps!
instablaster.
Hands down the easiest to understand IR spectroscopy vid I found on youtube. The explanation is clear and engaging.
It's 12:36am and I have my chem final at 9 tomorrow morning and I'd been flipping through my textbook and noticed IR spectroscopy, which I've never seen before, but which definitely will be on the final...so I'd just like to take this time to thank you for saving me about an hour of trying to understand this just from a textbook. Thanks for saving me time and energy!
did you pass?
Clare Maguire did you pass...
update: passed the course with an A+!! (didn't take me 4 months to get the results in though, only just noticed the replies now)
Clare Maguire oh yes!! Congrats!!! Tools my ochem 2 final today!
Give me no
You're truly a professor, IR has never been narrated so well to me
this saved my life, HL chemistry is kicking my butt and this is just what I needed. Everything is so clear when you explain it!!
lol i've done it for 4 semesters and i can totally relate
IB buddies!
This video changed my perspective from a neglected chapter in my Remote sensing course to me wanting to pursue a career in it.
Thanks a lot!
so smart...and such great hair..
hahahahah great hair !!!
a professor hair.
he's got the hippie hair tho.

Such a great explanation. Have been struggling to understand spectroscopy and so grateful I see ur channel

Im pretty sure my chem teacher has seen this video cuz he was dancing with his arm like that in class😂
It's the best way to explain it!
Totally agree :)
😅😅😅
Mine did too 😭
Chem Professor here, we all dance like this when we explain IR 😅😅❤️
so well explained! These videos are such classics, people have skipped comments for 2 years now but worth updating comments.
Professor Dave: talks very advanced science
Also Professor Dave: *swinging my arms asymmetrically is a very difficult thing to do*
this man just explained in the first 4 mins what my org chem 2 teacher in university right now couldn't explain in 5 classes.
I wish our university professor could explain and made lectures, topics this easy. These videos are really helpful. Thanks to Professor Dave.
needed this! we're going over NMR next week and i'm trying to get ahead :)
He explains more than my teacher. Keep it up Professor Dave, you ain't just covering the USA, but the entire world.
Everything becomes so much more clear after watching your videos! Thank you!
thank you so much for posting tutorials like this!
I was really confused when reading my textbook but
from this short 10 minutes video, I actually understood because your explanation was 🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒

That witheboard has borne an incredible amount of knowledge... thank you Prof. Dave!
You explain everything so well, thank you!
How did they figure this out at first?💀
That was easy to understand! Thank you, Professor Dave!
Brilliant prof. dave, you're the man! you should have way more views for this video. i'll be showing it in my lesson later today.
Watching this before our spectroscopy exam, thanks a lot sir .
I love you man! you literally saved me from failing
Ohmygod. I love all these videos. They're weirdly fun and knowledgeable to watch.
i love weird fun!
@@ProfessorDaveExplains me 👋👋
I am grateful for you Professor Dave
Well, Dave thank you for your great explaining. I practise english (listening) and learn chemistry thanks to your channel. Great job! 👏👏
Great teaching! Thanks from Brazil!
Thank you sir for after 4 years of college I finally understand IR well
thank you professor dave
Thank you! This is perfect, now I am aware of IR Spec and can be prepared for my quiz tomorrow
I am so thankful to you! We need more professors like you.
The first three minutes are an incredible summation of the theoretical principles of IR Spec 😮 I really wish I had known this existed when I was learning about it in class 😂
Holy cow, you explained this so well thank you!
thank you professor dave 🙏🏻🙏🏻 you're carrying my analytical technique marks rn
Prof. Dave saves the day once again.
This is very good
It has given me the very basic understanding than what my lecturer did
Do it into detail please
You deserve a nobel prize in education mate !
Hitting it out of the park. Thanks Dr. Dave
Thanks man, simple and understandable, but not so broad as to be not useful: 5/5 stars
Loved this! Thank you from Finland!
best explanation so far
Best explanation on TH-cam
YOU ARE WONDERFUL SIR,YOUR VEDIOS ARE SHORT AND CRISP.IS JUST TAKES FEW MINUITS TO UNDERSTAND THINGS WELL
I love your symmetric and asymmetric motions 😆
I saw your videos in first time .your video helped me a lot to understand spectroscopy.love from India
I had never understood IR spectroscopy until now, great Video 💯
you gave me a new insight into organic spectroscopy.
Thank you for a great video.
Now my concept is clear about ir spectroscopy thanks professor Dave ✅
Hey Dave.... You are really on of the best teachers in the world. And. the work you do is just extraordinary..... You're Great...... Your tutorials are really useful.....
thanks so much! happy to be of help
Your way of explaining things is really good.I enjoy viewing your lectures.
As a not-so-wise man once said, "Spectroscopy needs to be in a container."
Super...less time consuming.....quick understandable❤❤❤ respecting you master 🙏🏻🙏🏻🙏🏻
No words for how grateful I am. You are such a blessing💖
I followed you because of flat earth debunking videos. Now i am actually using your videos for my thesis work.
You are changing lives!
i liked this video before playing it because i already knew i was gonna fully understand IR spectroscopy afterwards
Thank you so much, congratulations for your great explanation. Can you make a video about emission spectroscopy?
i'll put it on the list!
oh! thank you sooo much! wohoo i survived! one of the best lectures that i ever had !
this will probably allow me to continue medschool! Thank you so much!
This video uses a graph inverse of what scientists here use. Instead of dips we use spikes. Otherwise it shows the same information. I finally figured out how to build molecules this way 2 days before the exam
thankyou sir , explanation is perfect 😍
Parabéns pela aula!!!!! Extremamente didático! Você merece muito sucesso!
Congratulations for the class!!! Extremely didactic! You deserve a lot of success!
Simple and great explaination , thanks a lot 🌸
I was struggling to understand. Well explained! Thanks a lot, Professor Dave.
Thank you Professor Dave for doing these videos!
Thank you very much:D Now I understand the IR-Spectroscopy. I wached so many videos but I just understand yours. :D
omg, thanks for the video. I couldn't understand what my teacher was trying to explain to me until this moment, hope I'll pass the exam c:
EVERYTHING U SAID MADE SENSE, LOVE YOU DAVE NO HOMO
It all makes sense now! Thank you so much!!
thanks Dave SO UNDERSTANDABLE
Oh what a lovely explanation . Thanks so much professor Dave ❤❤❤❤
Excellent explanation
I enjoyed that explanation. Happy Days.
sir you know everything 😀😀
but I don't know nothing 😢
but your lecture give me some knowledge 😇
Thanks Professor Dave
Concise and precise video
lifesaver honestly
Very lucidly explained
The vibrational modes occurring in syn- fase are symmetric, and those in anti-phase are ANTI-symmetric (not Asymmetric)
very nice explanation, thank you very much
What a nice chemist ever
It's 4am and I'm writing an oganic chemistry 2 exam today at 12pm. Using these to get me through it 🥺
This is what I needed. I always saved by your lessons!
A carbonyl group is C double bonded to O right? The functional group you identified on the right of the whiteboard is an sp2 C-H, which has a significantly different frequency (3050-3150) than carbonyl (1620-1680), which your drew in the spectra. I'm a little confused why you drew the carbonyl frequency in the spectra but identified it's functional group as a sp2 C-H instead?
A lifesaver. Keep up the great work
Thank you ❤️😃
Fans from Sri Lanka 🇱🇰😃
Great videos prof Dave! Keep it up
this video is amazing, thank u!! im studying for a test and helped a lot!! ~ Larissa- from Brazil
