Abstract
To reduce the problems in evalution of photokinetic rate equations, the liquid reaction system has to be stirred in order to get closed solutions. In the case of the examination of photoreactions in solids, the evaluation requires the application of numerical methods. In the special case of azobenzene in silgel 604A a further problem shows up, the photolysis product does not stay fixed at its site of production, but exhibits diffusion. It is demonstrated that even in this case an evalution is possible using modified rate equation, which take into consideration time and space dependencies as well.
