Heats of Formation of Radicals and Molecules by a Photoacoustic Technique

Article abstract of DOI:10.1021/ja00269a017

A photoacoustic technique was used to measure heats of free radical reactions.To illustrate the method, bond dissociation energies were measured for the Sn-H bond in n-Bu3SnH, for the C3-H bond in 1,4-cyclohexadiene, and for the C2-H bond in diethyl ether.Heats of formation of t-BuOPPh3 and t-BuOP(Bu-n)2 were determined, and the method was also used to measure quantum yields for the photolysis of di-tert-butyl peroxide and diphenyl disulfide.
