Abstract
The structures of the molecules SO2, CS2, and COS have been investigated by the electron diffraction method with the following results; SO2, S – O = 1.46±0.02A; CS2, C – S = 1.54±0.03A; COS, C – O = 1.16±0.02A, C – S = 1.56±0.03A. The types of bond arrangement compatible with these interatomic distances are discussed. In SO2 the molecule resonates between the structures having single‐double and double‐single bonds between the sulfur and the two oxygen atoms, with a bond angle of 122°±5°. CS2 is a linear molecule with the structure having the two double bonds predominating over those having a single and a triple bond. In COS the double‐double bond arrangement and the structure having the triple carbon‐oxygen bond predominate.Keywords
