Term Series for a Rotatinghyphen;Vibrating Diatomic Molecule by Perturbation

摘要

Expressions for the most important terms for the energy of a rotatinghyphen;vibrating diatomic molecule as a function of the coefficients of its potential energy, expressed as a power series, have been deduced by perturbation theory. The perturbation polynomials defined in this theory also enable one quickly and easily to calculate to a high order of accuracy the energy levels associated with any onehyphen;dimensional oscillator with a smooth, singlehyphen;minimum potential.
