摘要: Formulas for the angular momentum dependence of interaction matrix elements between rotating, nearly degenerate singlet and triplet electronic states are derived following conditions: (i) is first order, involving direct spin‐orbit coupling states; (ii) second occurring by a vibronic mechanism with in or manifold; (iii) spin‐rotation which interacting coupled to manifold intermediate orbital‐rotation coupling. Possible applications these formulas discussed.
