Hydrogen atoms have been generated in solution by photolysis of thiols in solutions of organic compounds, and the relative rate constants, kH, have been measured for the reaction H• + QH → H2 + Q•, where QH is any organic compound which contains hydrogen. This represents the first kinetic study of the hydrogen atom in which it is generated in solution by a technique not involving ionizing radiation. The relative values of kH are in agreement with the values from radiolysis for most of the substances studied; however, for some compounds significantly different results have been obtained.
