Calculate the contribution of the first excited electronic state, viz. 1Δ with ge=2, of the O2 molecule towards the Helmholtz free energy and the specific heat of oxygen gas at a temperature of 5000 K; the separation of this state from the ground state, viz. 3Σ with ge=3, is 7824 cm−1. How would these results be affected if the parameters Θr and Θv of the O2 molecule had different values in the two electronic states?
