Analytical or numerical solutions are given for the kinetic equations describing the time behavior of a solid photochromic film for the cases of photocoloration, photobleaching, and thermal bleaching. A procedure to evaluate relative quantum yields and absorption cross sections from the comparison of experimental results with theoretical solutions is demonstrated by an example using 6-nitro-8 piperidinomethyl-1', 3', 3'-trimethylspiro-[1H-benzopyran-2, 2'-indoline] as a photochromic compound. The theoretical results are presented in a suitably normalized form to be applicable to a broad range of experimental situations. The agreement between calculated and measured results is good as long as strictly first-order reaction mechanisms are obeyed.
针对描述固体光致变色薄膜在光致变色、光漂白和热漂白情况下时间行为的动力学方程，给出了分析解或数值解。通过以6-硝基-8-哌啶甲基-1',3',3'-三甲基螺[1H-苯并吡喃-2,2'-吲哚啉]作为光致变色化合物的示例，展示了一种通过将实验结果与理论解进行比较来评估相对量子产率和吸收截面的方法。理论结果以适当归一化的形式呈现，以适用于广泛的实验情况。只要严格遵循一级反应机制，计算结果与测量结果之间的吻合度就很好。
