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?
6. Consider the bond vibration of a homo-atomic diatomic molecule. In the harmonic approximation the vibrational energy levels are given by, Where v = 0,1,..., and w = 6.1 x 1014 5-1. Let us assume this vibrational mode is IR active. A photon of energy E = hc/, is absorbed by the molecule and induces a fundamental vibrational transition. (a) What is the wavelength of the resulting IR absorption peak in nm? [6 marks] (b) Is it reasonable to assume...
