• The decomposition of benzyl mercaptan and <I>p</I>-tolyl mercaptan in various organic solvents has been studied, and the following conclusions have been obtained. 1) A radiation-sensitive solvent such as hexane is readily attacked by the benzyl mercapto radical. 2) When the resulting mercapto radicals are stabilized substantially by resonance, solvent radicals from the radiolysis of solvents will abstract hydrogen from the mercaptan. 3) The <I>G</I>-values of mercaptan decomposition in such solvents as hexane, cyclohexane, acetone, methanol and dioxane are relatively higher than those in carbon disulfide, benzene, toluene and nitrobenzene. The reaction presumably proceeds through the energy transfer process from solvent to mercaptan. When an aromatic π-electron system is present in any solvent, the radiation energy absorbed will be dissipated quite readily through electronic excitation to lower-energy levels of the solvent molecule.
