In the previous paper in this investigation the first part (I) dealt with the mercury photo-sensitized decomposition of phosphine, and the second (II) with the sensitized photo-oxidation. Certain calculations and conclusions in that paper had to be left unfinished, until data on the direct photochemical reaction became available. The present paper, therefore, is devoted to the absorption spectrum, the direct decomposition and the photochemical oxidation of phosphine. The experiments are to some extent confirmatory of those involving excited mercury atoms but, owing to the simpler conditions obtaining in the direct reaction, it is possible to extend the calculations on the results to yield more information about the mechanism of the reactions.
