The energy of the vibrational modes of a molecule are the same as those of a (quantum) harmonic oscillator with frequency ω. There is a gas of nitrogen molecules in thermodynamic equilibrium for which ? / = 3340.

a) What fraction of the molecules are in the ground state, the 1st excited state, and the 2nd excited state of their vibrational modes at a temperature of 800 K? Use the exact partition function for this part.

b) At what temperature will 4% of the molecules be in the 1st excited vibrational state? You may approximate the vibrational partition function with the largest two terms in it.
