## Approximate analytical expressions for the evaluation of the partition function of an anharmonic oscillator characterized by the spectroscopic energy formula E, = hc[w,(n + f)-oex,( n + i)'] have been suggested. By using these expressions partition functions for a set of representative diatomic

The problem of the representation of the RKR (or IPA) diatomic potential by a simple analytic function is considered. This old problem has for a fairly good solution the Coxon-Hajigeorgiou function U(x) = D(lexp( -fn(x)I2 withf,(x) = Ck=, a,P. The problem of the determination of the disposable param
