Photokinetische Untersuchungen an den photochromen Systemen der Dihydroindolizine

Abstract

The dependence of partial photochemical quantum yields on temperature and light intensity was examined with two dihydroindolizines. Some nonlinear optimization procedures and least squares methods are used to solve the system of differential equations. The distinct influence of the competitive thermal reaction can be demonstrated for both photochromic systems by determination of thermodynamic and kinetic parameters.
