Hund's coupling case (c) in diatomic molecules. II. Examples

Abstract

For pt. I see ibid., vol. 6, 1479 (1973). A theoretical discussion of the rotational energy and fine structure of Hund's case (c) states in diatomic molecules was given in Pt. I. In this paper the theoretical results are applied to several electronic states of heavy diatomic molecules. The states chosen are the E1/2 and F1/2 states of YbH and YbD, and A2 pi , B2 Sigma and C2 Sigma states of HgH and the x3 Sigma - ground states of AsF and SO. This variety of states exemplifies several aspects of the theory, which in particular for the 3 Sigma states gives a much more the traditional Hund's case (a)-(b) model.
