Abstract
The structures of the gas molecules of ketene and thiophosphoryl chloride have been determined by the diffraction of 57 kilovolt electrons. The interpretation of the photographs was made by the visual method in conjunction with the radial distribution method. The results for ketene are: carbon‐carbon distance 1.35±0.02A., and carbon‐oxygen distance 1.17±0.02A. The carbon‐hydrogen distance was assumed to be 1.07A. The results for thiophosphoryl chloride are: phosphorus‐chlorine distance 2.01±0.02A, phosphorus‐sulphur distance 1.94±0.03A, and the Cl–P–Cl angle 107±3°. The results are discussed in terms of covalent radii and the resonance of molecules among several electronic structures.Keywords
