Worksheet: Rovibrational Energy Levels
In this worksheet, we will practice calculating diatomic energy level spacings from the vibrational frequency and rotational and centrifugal constants.
The vibrational frequency of the oxygen molecule is s−1. In the vibrational partition function, the energy of the lowest vibrational energy level is set to zero and all other vibrational energies are calculated relative to this value. Using the harmonic oscillator approximation, calculate to 4 significant figures the vibrational partition function for the oxygen molecule at 1,000 K.
