Abstract
Rotational structure in five bands, viz (0,0)1/2, (0,1)1/2, (0,1)3/2, (1,0)3/2 and (0,2)3/2 of the B-X system of the silicon monochloride molecule has been analysed by photographing the spectra in the third order of a 10.6 m concave grating spectrograph (dispersion 0.22 A/mm). The rotational constants of the states participating in the transition are obtained as follows: Be'=0.2791+or-0.0003 cm-1; De'=1.8*10-7 cm-1; alpha e'=0.0020 cm-1; Be"=0.2561+or-0.0001 cm-1; De"=2.30*10-7 cm-1; alpha e"=0.0015 cm-1; lambda -type doubling in the 2 Pi 1/2 component=0.006 cm-1. The spin splitting in the excited state is found to be of negligible magnitude. The weak isotopic lines due to 37Cl have also been detected.Keywords
