✦ Synopsis

205 reaction hV T--)B? A A method is presented for the kinetic analysis of the reaction system A TB which uses the dependence of the photostationary state on the temperature. One kinetic measurement yields the reaction rate constants of the thermal reverse reaction at various temperatures, thermodynamic data and the spectrum of photoproduct B. The knowledge of the absorption coefficient of the photoproduct allows the photochemical quantum yield to be calculated by numerical integration of the rate law.

To obtain an indication of the significance of the data, the method is tested using sets of simulated data and is finally applied to the photochromic systems of some dihydroindolizines.

## Abstract A method is proposed whereby the orders and rate constants for processes obeying the rate law βˆ’__dA__/__dt__ = __kA__^n^ may be determined. The method is illustrated in two ways. First, simulated data for processes of various orders are treated, and the treatment is shown to be capable
