Abstract

S3O is the most recently discovered sulphur oxide, detected in the gas phase by neutralization of the S3O+ ion in neutralization-reionization experiments (NR). Very recently high-level theoretical calculations predicted that ring structures are the most stable minima on the singlet S3O and doublet S3O+ surfaces. On this basis, it was claimed that the species detected by NRMS was the ring S3O rather than the cis open-chain, less stable than the ring by 2.6 kcal mol-1. However, the NR spectrum shows that both the S3O oxides are formed by neutralization and survive for a time period of at least 1 microsecond.
