Abstract

This article focuses on the computational investigation of the [H, Cl, S, O] molecular system relevant to the Venusian atmosphere, providing detailed spectroscopic parameters and stability analyses of its isomers. Using high-level coupled cluster and multi-reference methods, six isomers were characterized, with HOSCl identified as the most stable and only HOSCl and trigonal-HSOCl being thermodynamically stable relative to the dissociation limit HCl + SO. The study finds that these isomers exhibit complex vibrational spectra due to anharmonic resonances and are photostable in the visible region, indicating they are unlikely responsible for Venus's near-UV absorber. The provided spectroscopic data aim to support future laboratory detection and astronomical searches, contributing to understanding sulfur–chlorine chemistry in planetary atmospheres.
