✦ Synopsis
A quantum chain reaction is a photochemical reaction in which electronic excitation is cycled through a number of steps.' This concept has been employed 2,3 to explain the concentration dependent kinetics of the thennal decomposition of tetramethyl-1,2-dioxetane (TMD).4 We report here that (a) the photochemical decomposition of TMD also involves a quantum chain reaction; (b) the experimental quantum yields for decomposition of TMD exceed 200 and approach 1000 in the limit; and (c) a kinetic analysis of the photodecomposition of
