Abstract

Abstract: Traditionally, the general photochemical rate equation could be integrated only at two limits (high concentration and low concentration). In this paper, the general photochemical equation has been integrated to yield a master equation that is valid for any chromophore concentration. Hence, in future, data for all concentrations can be utilized in deriving the incident photon flux and/or the quantum yield for a photochemical reaction. Unfortunately, the master equation can only be used for monochromatic light sources. Abstract : In the past, the analysis of photochemical rates has only been possible approximately in the high‐ and low‐concentration ranges (see figure). This paper derives a Master Equation that allows an exact analysis over the entire concentration range using a function (see black line).
