TL;DR: In this paper, photoelectron spectra of gaseous products from reactions of atomic/molecular bromine with powdered sulfur and selenium were analyzed with a visual assessment stripping program (VASP).
Abstract: The photoelectron spectra of gaseous products from reactions of atomic/molecular bromine with powdered sulfur and selenium analysed with a visual assessment stripping program (VASP) yield the He(I) spectra of SBr 2 (sulfur dibromide) and SeBr 2 (selenium dibromide). The proposed assignments are consistent with the results of valence-electron-only model-potential (VEOMP) calculations.
TL;DR: When sulfur dichloride or disulfur-dichloride vapour is diluted with argon and mixed with bromine or iodine, the products are isolated in an argon matrix at 9 K as mentioned in this paper, and the infrared spectra of these products show absorptions which are assigned to unknown sulfur dibromide SBr2 and sulfur diiodide SI2, respectively.
