How could you estimate a vibrational temperature from a Raman spectrum?
Show explicitly what lines will occur in a Raman spectrum in which the vibrational number of the molecule changes from v=0 to v=1. Then describe in qualitative terms how this spectrum differs from a vibrational-rotational spectrum.

Raman spectrum of an adduct. Help quick. When it says references it just means that you should look at them, but don’t need to cite them necessarily. Thank you.

You have in your posession the first vibrational spectrum of a new diatomic molecule X_2 obtained at 1000 K. From the spectrum you determine that the fraction of molecules occupying a given vibrational energy state n is as follows: What are the vibrational energy spacings for X_2?
Vibrational spectrum of H-CI: theory Calculate the vibrational amplitude of a state: al amplitude of a H-Cl molecule in its ground state, and in the first excited a) Describe in words or sketches what needs to be done. b) Create a symbolic expression for the vibrational amplitude (this would be the first step of calculating a numerical value). c) Almost all crystals have a positive coefficient of thermal expansion. In other words, they expands when you heat them. Use the...
