Notes: Determination of the Molar Absorptivity (ε) of the Photoisomers of 3β-Hydroxy-cholest-5.7-diene (Provitamin D3)A method is described which allows the determination of the molecular absorptivity (ε) of all components in a four-component system and is applied to the ε-determination of the photoisomers of provitamin D3 (1): prävitamin D3 (2), lumisterol3 (3), and tachysterol3 (4). By means of irradiation with appropriate wavelengths the four-component system is reduced to a two- and a three-component system, respectively, and the unknown molar absorptivities are evaluated numerically or graphically.
