Multiple time scales in pulse radiolysis. Application to bromide solutions and dipeptides

A description is given of how multiple time scales are incorporated into a new computer program for running pulse-radiolysis experiments on a linear accelerator. For any kinetic trace, the data can be presented on ten distinct time scales. The algorithms for doing this are presented. The utility of this procedure is illustrated with the radiolysis of bromide solutions. The kinetic traces are discussed in terms of formation of a BrOH√⁻ adduct and its approach to equilibrium with Br√⁻₂. A second example, with the radiolysis of a dipeptide Met–Met, illustrates the ease of simultaneously determining the yield and decay behavior.
