A new potential function for diatomic molecules

Новый потенциал для двухатомных молекул

Abstract

An empirical potential function for diatomic molecules is given. The conditions to be satisfied by such an empirical potential function, as derived from physical considerations, are determined and some of the potential functions used previously are briefly discussed from this point of view. It is shown that the solution of theSchrödinger equation for theMorse potential, as used extensively, is not exact. The new potential function suggested by the authors, satisfies the required conditions and leads to an exact solution of theSchrödinger equation. The considerations are restricted to the vibration spectrum.

Резюме

Потенциал двухатомных молекул целесообразно определяется эмпирически. Резюмируем кратко условия — получимые из физических соображений — которыми потенциал должен удвблетвотять и на основе этих условий дискутируем некоторые применяемые потенциалы. Докажем, что общепринятое уравнение Шредингера с потенциалом типа Морс с математической точки зрения некорректно. Даем новый потенциал, удовлетворяющий налагаемым условиям, с которым уравнение Шредингера решимо точно. Наша трактовка ограничена на колебательный спектр.
