11 years later, this very niche video is still helping people. Thank you, this video is wonderful!

polarizability is simply the ability of a molecule to have it's electron density deformed, an asymmetric stretch would not deform the density it would only shift it in one direction, changing the dipole, but not changing the polarizability too much

Holy shit, I didnt get why sometimes it's IR active and sometimes it isnt but i get it now. You're great, lady, omg I owe you my life I love u.

It's because the polarizability from the stretch on one side of CCl4 is "canceled out" by the compression of the other C-Cl bond in the asymmetric stretch, so there is little change in polarizability overall in that particular vibrational mode.

4:44 Yes, and this (CO2) mode is registered clearly by Raman Spectroscopy. Why isn't that stated?

Confused on the Raman part. So change in polarisability needed for raman (due to change in shape/electron cloud position), would this not suggest that the asymmetric stretch would be more raman active as the shape change is more significant, as the structure is no longer a symmetrically linear geometry? This video did help clear up alot for me though thanks! Any response would be appreciated as i have my exams on this in a few weeks! :)
