The vacuum ultraviolet absorption spectrum of bromosilrtne in the vapor phase is reported. Assignments are made using photoelectron data and oscillator strengths. The absorptions of this compound are related to absorptions of chlorosilane, methyl bromide and methyl chloride. The results of this work

β¦ Synopsis
The h~ain features in the electronic spectrum of OCSe in the vaauum ultraviolet region (A = 200-118 nm) are reported and assigned. Bands of overlapping Rydberg series etiibit extiemely complex structure involving spin-orbit coupling (ca. 1800 cm-'), weak excitation of the high frequency stretchi@ vibr:;tion (ca 2100 cm-') and progressions and sequences in the low frequency stretch (ca. 500 cni-*). Wit\ the help of the He 1 photoelectron spectrum Rydberg series, which corre- spend to Rydberg levels closely similar to those of 'AC SC atom and of CSe2, are assigned. Suggested assignments of the remaining stroni features to intra-valence transitions aro.made.

Based on ab initio configuration interaction calculations and the previously measured vacuum-ultraviolet spectrum of ethylene sulphide, we have been able to assign essentially all absorption peaks, including the s, p and d Rydberg series up to n=9.
