Rotational and predissociation lifetimes of the A^2∑^+ state of OD*

Abstract
The lifetime and predissociation probabilities of various rotational levels of the A 2+ state of OD were measured. A strong predissociation at N′ = 35 was observed. This predissociation could be explained by the level crossing of the A 2+ state with the repulsive 4 state which are mixed by a weak spin–orbit interaction.
