Great explanation 👍
@27:04 You speak 10mm to the left and 10mm to the right, but your caption indicates 0.2cm. What am I missing here?
Thank you! It really helped me prepare for my presentation. The quality of the presentation is outstanding!
Thank you
classic video
Great!
You are the only person who has ever made this make sense to me and somehow made the content not boring. Please do more of these videos you’re saving my grade
Imma need u to teach PH and PKA problems bc I actually pay attention to you
This is AMAZING
Certainly one of the best UA-cam channels on chemistry topics. I love that the presentations are not oversimplified, which would result in the loss of some information vital for the understanding of the topic.
Thank you for your positive comments.
High quality presentations and the inclusion of the links, used software and even the used fonts... I LOVE these lectures
Really enjoyed this presentation. Many thanks for your work, I greatly appreciate it!
Excellent explanation. Combined with the Fourier transform description, lectures clarified how the FTIR works. Thank you.
excellent
One of the best presentations of FT, but i still din't understand why need to use interferometer, can we just use different frequencies of light are shone on the sample simultaneously then do FT? why need interferometer.
That could be done. However then you need either a diode array detector or the machinery to move a diffraction grating so that the light crosses a detector as the grating moves. In that case you would not need FT as you are analyzing the energy at each discrete wavelength. UV-vis spectrophotometers use this method. IR wavelengths make the use of the interferometer convenient and less expensive than continuous wave systems (like UV-vis). Diffraction gratings for IR are difficult to make but not impossible. I myself am not familiar with all the limitations and advantages of both approaches but clearly for IR the industry has chosen interferometry for its effectiveness, cost and convenience in this wavelength range.

@9:52 So does the mass stay the same as you go up in the morse potential? In 8 years surely someone has done the math.
Yes the mass remains the same. It is the energy that is increased.
Total of 10 hours of teaching by my professor, compressed into a 5 minute video by you. Thank you !!!
nice presentation, thank you a lot
I looked through a lot of crappy IR videos, this one is much better. Thanks for the presentation.
awesome explanation
Thanks a lot!, I was looking for a clear and precise explanation like this
Thank you very much!! Very clear ans concise explanation of the content🔝
This gave me a whole new way of looking at bonding! Nobody ever told me about the overlapping circle thing. My question is what do the different colors represent? Why do we subtract when the opposite color circles overlap? I have some ideas, but I don’t want to give myself a false understanding.
The different shading represents the sign (positive or negative) of the wave function. If we want to have constructive interference (addition) we combine them with the same sign. The other option is destructive interference (subtraction) where we add opposite signs together. Every pair will combine both ways. The constructive combination is lower in energy. Some orbitals (eg pi orbitals) have lobes with opposite sign, that is why these orbitals have two shades.

One of the best presentations of Fourier transform applied to spectroscopy. Not only that, but apodization, resolution, etc. Thank you for making this so well!!
Do you know why FTIR need interferometer?
Aren't the names of the "sigma" and "pi" MOs derived from the names of the corresponding AOs (provided they interact correctly)?
The AOs used to create the MOs are sp^n hybrid orbitals and p-orbitals. The sigma and pi nomenclature applies to the MOs that they create when combined. You can make a pi orbital from two p-orbitals (side-to-side) or a sigma orbital (end-to-end combination of two p-orbitals).
@@keynotechem I am aware of that. You gave me the impression that the Greek names actually refer to special types of symmetry, which seemed a bit confusing.
taking the red pill is never easy but I loved the lecture! Thanks so much! :)
What is the name of the font you use?
I used "Sketch Rockwell" and "Architects Daughter". Both are free to use for non-commercial purposes.
@@keynotechem Thank you!
Bringing NMR into the public sphere. Awesome.
The best presentation I've ever seen!
For FTIR instrument, the IR source come with single or multi wave length?
Great vdo!
Good
정말 도움이 됩니다. 감사합니다. (Very helpful! Thank you!)
really good lecture!
Thank you for your contributions sir.
Hello, Thank you for the great video.. I have a question, at 8:20 when you slide backward the moving mirror then how did the coming back (left) signal cancelled down from the moving mirror? Shouldn't it be cancelled at the other end of the splitter?
Very good presentation
cool and interesting!
very informative
good
very interesting
Awesome video!
This is so cool!
HOW DOES ELECTRIC FIELD CAUSES A CHANGE IN THE DIPOLE MOMENT ?? HOW DOES IT INTERACT ?
This is lovely. Thank you so much
marvelous !
Excellent explanation. Much appreciated.
The fact that this was made before the first GWs were "seen" with interferometers OMG
