Abstract
The N.M.R. spectrum of tetraphosphorus trisulfide was investigated in various solvents. The observed variations of the chemical shift of the P4S3 multiplets, which can be as large as 34.5 ppm, are caused mainly by dispersion interactions. Here the interaction of the directly bonded phosphorus atoms of the P4S3 molecule is as large as with dissolved white phosphorus. No variation of coupling constant JPSP with the various solvents could be observed; this coupling constant was found to be 71 ± 1 Hz. Further the solubility of P4S3 in some solvents is given.
