Abstract
The limitations of the generally accepted photostationary approximation in the photochemistry of provitamin D resulting from the strong spectral dependence of the effectiveness of the irreversible channel were established theoretically by a simplified model. The results show clearly that disregard of the irreversible channel with low quantum yield in a system of reversible photochemical reactions over a wide spectral range is not always justified. As a result the approximation according to which the concentration of the main photoisomers of provitamin D is constant only holds in a specific region of the spectrum, and this must be taken into account during concentration analysis of the photoisomeric mixture.
