Аннотация:The simple expression [v’\textbackslashfDELTAU(n)g\textbackslashv’] is offered to approximate sums of the form SIGMA(v”=0)infinity [v’\textbackslashf\textbackslashv”] [v”\textbackslashg\textbackslashv’](E(v’)-E(v”)n, where f and g are some operators which couple the vibrational levels v’ and v” of two interacting electronic states and DELTAU = U’- U” is the difference of the corresponding internuclear potentials. The rigorous quantum proofs as well as semiclassical justification of this formula are presented and its absolute accuracy is estimated in a closed functional form. Invariant properties and spectroscopic applications of the sum rule, including the evaluation of lifetimes, fine-structure (LAMBDA-doubling) constants, and Lande factors, are discussed.
