Abstract
In a series of emission, absorption, and fluorescence experiments on the C 2Σ+ state of NS it is shown that the intensities of bands originating from v′=1 and 2 levels are less (relative to v′=0 band intensities) than is expected on the basis of Franck–Condon factors. This weakening is attributed to predissociation and an upper limit of 45 380 cm−1 is obtained for De, the ground state dissociation energy. Correlations of NS states with those of NO are made and possible mechanisms of predissociation discussed.Keywords
