Evaluate the vibrational partition function for NH, at 1000 K for which the vibrational frequencies are 950, 1627 (doubly degenerate), 3335, and 3414 cm-' (doubly degenerate). Can you disregard any modes in this calculation? Why or why not? Information you may find useful: h = 6.6261-10-» Js,kB = 1.3806-10-23 J-K-1.
