10:40 CO2. The first is the 2349cm-1 of CO2, and at 12:35, this is CO2's Raman active mode at 1380 cm-1. The last is the 667cm-1 ( the one that lies within the Earth's blackbody curve). The 1380cm mode can now be detected with modern laser technology and Raman Spectrometers, and so can the modes of the diatomic molecules Nitrogen and Oxygen at 2338 and 1556 cm, respectively. This should collapse greenhouse theory, where these modes are assumed not to absorb and emit.
So do diatomic molecules have natural resonant frequencies OR rotational frequencies at every quanta of energy level? I missed my understanding here ... ?
GOD!! why no one taught me chemistry like that. I hated chemistry before watching this video, as a physics lover, chemistry was always a turnoff for me because I felt it was just rote learning and no understanding.
"Chemistry alone wasn't a descriptive enough name, so we pulled some idiotic naming out of our asses to satisfy our pathological compulsive obsession with acronyms, especially those that look remotely like actual words in this retarded trainwreck of our language, and also totally jizzed our pants when we noticed we even made a recursive one" - Murricans, early 1960s
Never seen a more beautiful & comprehensive explanation than this.
the best channel for studying real chemistry, not just bookish theoretical stuff nowadays
this is an excellent explanation for the different mode of vibration in a molecule ...great .....
Fantastic ball-stick representation of vibrational spectroscopy. Thanks a lot.
Great lecture. Excellent explanations.
Great Job ..fantastic explanation ..thank you professor
Great video, excellent methods of demonstration and teaching, much better than computer generated models these days. What year is this from?
Loved it... Got me interested in learning spectroscopy
Really a helpful hand to understand molecular spectroscopy.
one of the best explanations!
Outstanding video!
Thanks
Thanks Phil, glad you enjoyed it!
Wondeful video!
awesome lecture
great lecture
Excellent explanation sir

It says 1962 in the bottom of the screen at 0:13 seconds

science is factual

Let me paint you a picture to illustrate how much of a fuck I give:
Shall I show you that picture again?
why am i not shown this in class????????
Awesome lecture
