LIX.Note on the interrelation of the equilibrium nuclear distance with other molecular constants for diatomic molecules

Abstract

Summary CERTAIN data from band-spectra are shoran to lead to a general relation of the form re = re (ω e , xe , D e , μ), between the nuclear distance, re , and certain other molecular constants. Empirical relations have been set up in the form re = re (ω e , and re = re (ω e , μ), and are therefore of a less general type. To establish the empirical relations on a theoretical basis it is necessary to carry out an investigation into the general properties of the potential curves of diatomic molecules. Certain suggestions are made as to the type of procedure that may prove sufficient for our purpose, but the detailed analysis will appear in a subsequent paper.
