✦ Synopsis

A new generalized potential energy function is suggested for dlatomic moleculer The Dunham. Simons-Parr-Ftilan, Thakkar and Ogilvie potenrials are shown to be particular cases of the generalized potential energy funcrion. II is also shown that the functron suggested may reproduce the path of the potential curve mith sufticient accurac_v even for the cases of small expansion length. The construction of an accurate analytical Born-Oppenheimer potential energy function for diatomic molecules from experimental data 1s an important problem in molwular physics. The potential energy function is frequently presented as a power series-( n v=g& 1 + c giMJ , i=l > (1) in which w is a function of the internuclear separation R, and coefficientsgi are calculated on the basis of the analysis of observed vibration-rotation spectra.

The properties of the long-range part of the previously suggested generalized potential energy function and Coulomb-subtracted generalized potential energy function have been investigated. It is demonstrated that these empirical functions can correctly reproduce the long-range part of the diatomic p

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
