Thanks for your reply! For diatomic molecules I would have used these steps and formulas to calculate the heat capacity. However, it was carbon-dioxide in this problem, which was a polyatomic molecule, and I did not find anything relevant from the statistical physics books. That is why I tried...

Homework Statement The carbon-dioxide has nondegenerate vibrational energies εr=（h/2π）ω(r+1);r=0,1,2..., where ω=(1.26*10^14)s^-1. What is the contribution of these vibrational modes to the molar heat capacity of carbon-dioxide gas at T=400K? Homework Equations...
