摘要
The origins of the predissociations observed by Smith, Brzozowski, and Erman for the A3Πand c1Π states of NH have been investigated via a Franck-Condon analysis. It is shown that the measured variation of the predissociation probability is is proportional to the Franck-Condon densities between the bound rotational levels of the A and c states and the vibrational continuum of a 5Σ- state arising from the ground state asympote. Similar calculations for the X3Σ- ground state vibrational continuum, the only other state with a lower dissociation limit, showed that state to be ineffective in producing the observed predissociation. © 1979.
