Decades after learning about IR, I was reviewing a package of data that purported to confirm that a plant-based oil met all USP NF specifications for pharmaceutical use when I noticed that contrary to analyst claims, the IR spectra clearly did not match that which was presented in the Compendia. Everything else in the data package agreed. So I flipped a page and found a match to another oil, but then all the other tests would not agree. I took the liberty to call the NF and they confirmed that the spectra were inadvertently switched and would be corrected in their next publication. The raw material was good to go. Don't fake anything. The Establishment is Fallible and we should not fear to question it.
Thank you so much for guiding this well. Can you make a complete tutorial video sharing the process of smoothing an FTIR peaks in origin and then, analyzing it just the way you are analyzing the graphs in this video. I got my FTIR results but looked quite distorted so I used Origin software's smoothing and Peak analyzer tools to find the peaks. The resulting graphs do not look like the ones you are showing in this video. How should I interpret them?
I mean he has the actual structures so he’s not going to be wrong. And plus those peaks are 2800 and 2600 which aren’t the ones required for aldehydes.
About five years too late, but the first spectrum is missing the carbonyl stretch, so that can't be an aldehyde. The second very well could be; the hydroxyl and carbonyl groups are not necessarily linked. I'd need more information to decide!

What a good video. Straight to the point and exactly what I was looking for. Keep it up man!
How old are you? Hahaha. I see u two times in the comment 😂😂🤣
I could not gain information from vedio.any one konsy guide me plz
This is wonderful Thank you so much you will help me pass my degree.
don't lie

great boss, thanks much
Bhut Hard
butt hard
I like your class sir
Hi,
I need help just wanted to know if I analyzed my sample in the right way or not?!
Could you please help me with that
Thanks a lot ........
Is it possible that this is actually an aldehyde? Aren't they at about 2700-2800 with two peaks?
Yes, I believe he is wrong. That is an aldehyde I believe.

What functional group is responsible for a peak at (1690 - 1715 cm^-1 ) ?
C=O (Carbon double bond to Oxygen)
Stretching frequency of functional groups in benzaldehyde, acetophenone, ethyl acetate, aniline and methyl amine
Please answer me
Very good
Thanks so much
I don't understand 2:08 how does he know it's c triple bond n instead of cc?
the CN triple bond has more peak than CC, the CC triple bond should be a bit weak in the peak
Superb
