Abstract Competing first‐ and second‐order reactions of transient molecular species (e.g., triplet states and free radicals) are a common occurrence in kinetic studies such as flash photolysis and pulse radiolysis. We have developed a method for analyzing the decay kinetics of any species ( Y ) whose disappearance is described by − dY / dt = k 1 Y + k 2 Y 2 . The computer program (written in time‐sharing BASIC) employs an iterative technique to obtain the least‐squares estimates of the three parameters in the integrated rate equation.
