Abstract

An investigation of the infrared spectrum of gaseous thio-thionyl fluoride (SSF2) results in the following assignment of fundamentals: A': v1 760.5�0.2cm-1, v2 718.5�0.2 cm-1, v3 411.2�0.4cm-1, v4 364.1�0.3 cm-1. A": v5 692.3�0.8cm-1, v6 337.6�0.4 cm-1. A normal coordinate vibrational analysis has been performed and a set of ten force constants evaluated. Some conclusions are given regarding the electronic structure of SSF2. Thermodynamic functions based on the usual assumptions have been calculated for SSF2. A set of potential constants has been evaluated for disulphur monoxide, SSO, using the available infrared data.
