Radiative transition probabilities for the A 1Σ+–X 1Σ+ bands of 7LiH

Abstract

The recently reported hybrid potential curves of Stwalley et al. [J. Chem. Phys. 66, 5412 (1977)] for the X ¹Σ⁺ and A ¹Σ⁺ states of LiH are combined with the ab initio transition moments of Docken and Hinze [J. Chem. Phys. 57, 4936 (1972)] to calculate radiative transition probabilities between all upper (v′?26) and all lower (v^″ ?23) vibrational levels of ⁷LiH. By far the strongest single band found is the 23–26 band between the highest ’’long‐range’’ levels in each potential. A comparison with experimental intensity observations is made; it appears that the experiments are globally in accord with our calculations, but with some detailed differences discussed herein.
