The importance of ‘‘Hot Radical” processes in the photolysis of liquid methyl iodide is further evidenced in the formation of methane and ethane as gaseous products. For the reactions induced by light at 2537 A. the quantum yield for the formation of methane is 0.023, while that of ethane is 0.007. Although the iodine concentration is increasing during the course of the reaction, the ethane and methane yields are found to be independent of the extent of irradiation. The gas yields are dependent upon iodine concentration only at very high iodine concentrations. At room temperature, these yields are independent of the temperature of the sample. Methylene iodide is shown to be a product of the photolysis, while little or no hydrogen, ethylene, or acetylene formation is observed.
