Temperature Dependence and Photochemical Reaction Mechanisms

The hydroperoxide quantum yield in the temperature range studied has been found to be close to unity and temperature independent. It has accordingly been suggested that radical chains are absent under the experimental conditions used. With increasing temperature, hydrocarbon oxidation becomes a chain reaction with predominance of final oxidation products. 

The primary processes of photochemical mercury-sensitized reactions of various classes have been discussed in detail [75].
