Diatomic Potential Functions Derived from Accurate Fits to Vibrational Energy Levels Using Algebraic Theory

摘要

Algebraic theory is used to fit the set of bound vibrational energy levels of H_2 and its isotopomers, up to the dissociation limit and to an accuracy of within 1 cm~(-1) in each case. Coordinate space potential functions are constructed from these algebraic Hamiltonians, and the limitations of the algebraic approach are assessed.
