Ring and open-chain S3O sulfur oxides are detected by neutralization–reionization experiments. The paper reports experimental results that differ from the conclusions of a previous theoretical study (Chemm.Comm. 2005, 3712), and succeed in providing the definitive experimental assignment of the structure of S3O and S3O+. A simple labelling experiment gives strong evidence that the open-chain structure is detected and not just the ring one.
