II: Properties of Diatomic and Triatomic Molecules. A theoretical study of the X 6Σ+, A 6Σ+, and 6Δ states of CrH
Results are presented from a theoretical study of the X6‡+, A6‡+ and 6j electronic states of CrH using multiconfiguration second-order perturbation theory in the multi-state formalism (MS-CASPT2). It is shown that the results for the spectroscopic constants and radiative lifetimes for the A state are in agreement with experiment and an earlier multireference configuration interaction study only if
