THE ABSORPTION SPECTRUM AND DISSOCIATION ENERGY OF SH

Abstract

The (2,0) bands of the A2Σ+−X2Π system of SH and SD have been photographed for the first time. More accurate values for the vibrational constants of the A2Σ+ state have been obtained. The dissociation energy of SH in the excited state is [Formula: see text] from which it is possible to deduce that the ground state dissociation energy [Formula: see text] (SH) is 28,480 ± 1000 cm−1 (81.4 ± 2.9 kcal/mole, 3.53 ± 0.12 ev).
