Abstract

Equations are obtained relating the isotopically invariant spectroscopic parameters Umj, which must be considered as conditions in the least-squares method in spectral analysis. Expressions are given for the first seven Dankhem potential parameters in terms of Um0 and Um1. The contribution to the spectroscopic coefficients Ymj due to violation of the Born-Oppenheimer approximation is calculated for12C16O.
