IR Spectroscopy

- Well, this is weird. What are all these squiggles? Those peaks represent the wavelengths of infrared light that don't get to the detector, because there's some functional group in the sample absorbing them. Professor Dave busts out some dance moves in this one. Do the symmetric stretch!

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.
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 :)
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.
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.
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
Hands down the easiest to understand IR spectroscopy vid I found on youtube. The explanation is clear and engaging.
so smart...and such great hair..
hahahahah great hair !!!
a professor hair.
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!
You're truly a professor, IR has never been narrated so well to me
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!
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!
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 😅😅❤️
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 !
Such a great explanation. Have been struggling to understand spectroscopy and so grateful I see ur channel
Your video was so helpful and I love your enthusiasm!
I wish our university professor could explain and made lectures, topics this easy. These videos are really helpful. Thanks to Professor Dave.
Everything becomes so much more clear after watching your videos! Thank you!
needed this! we're going over NMR next week and i'm trying to get ahead :)
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.
You explain everything so well, thank you!
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.
so well explained! These videos are such classics, people have skipped comments for 2 years now but worth updating comments.
That was easy to understand! Thank you, Professor Dave!
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
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 🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒🖒
I am so thankful to you! We need more professors like you.
Hitting it out of the park. Thanks Dr. Dave
Loved this! Thank you from Finland!
you gave me a new insight into organic spectroscopy.
Thank you for a great video.
Your way of explaining things is really good.I enjoy viewing your lectures.
I was struggling to understand. Well explained! Thanks a lot, Professor Dave.
Thank you Professor Dave for doing these videos!
Holy cow, you explained this so well thank you!
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!
😂
Thank you very much:D Now I understand the IR-Spectroscopy. I wached so many videos but I just understand yours. :D
Watching this before our spectroscopy exam, thanks a lot sir .
Professor Dave: talks very advanced science
Also Professor Dave: *swinging my arms asymmetrically is a very difficult thing to do*
I am grateful for you Professor Dave
Great teaching! Thanks from Brazil!
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 😂
Thank you! This is perfect, now I am aware of IR Spec and can be prepared for my quiz tomorrow
Well, Dave thank you for your great explaining. I practise english (listening) and learn chemistry thanks to your channel. Great job! 👏👏
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 😆
Thank you so much, congratulations for your great explanation. Can you make a video about emission spectroscopy?
i'll put it on the list!
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
I had never understood IR spectroscopy until now, great Video 💯
Super...less time consuming.....quick understandable❤❤❤ respecting you master 🙏🏻🙏🏻🙏🏻
Prof. Dave saves the day once again.
Parabéns pela aula!!!!! Extremamente didático! Você merece muito sucesso!
Congratulations for the class!!! Extremely didactic! You deserve a lot of success!
I love you man! you literally saved me from failing
Great videos prof Dave! Keep it up
Ohmygod. I love all these videos. They're weirdly fun and knowledgeable to watch.
i love weird fun!
@@ProfessorDaveExplains me 👋👋
Thank you sir for after 4 years of college I finally understand IR well
He explains more than my teacher. Keep it up Professor Dave, you ain't just covering the USA, but the entire world.
Simple and great explaination , thanks a lot 🌸
very nice explanation, thank you very much
Thank you, this was so helpful!
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.
you always make great videos but this one HIT! tysm 🤩🤩
Now my concept is clear about ir spectroscopy thanks professor Dave ✅
This is what I needed. I always saved by your lessons!
Thank you, Dave!
wow! amazing! it explains almost everything in my mind...
A lifesaver. Keep up the great work
this will probably allow me to continue medschool! Thank you so much!
Oh what a lovely explanation . Thanks so much professor Dave ❤❤❤❤
