Our journey, so far, has led us to develop a better understanding of photokinetics through the development of various strategies. Nonetheless, the efficiency of solving photokinetics remains limited, mainly useful for relatively simple reaction mechanistic options. And among other matters, two important ideas have become self-evident. The first relates to a lack, in photokinetics, of integrated rate-laws, and the second, inferred from the first, stipulates that when the integrated rate-equations are available, they considerably simplify both data treatment and kinetic elucidation.
