✦ Synopsis

Abstract

Kinetic experiments on the isomerization of lumisterol~2~ under the influence of ultraviolet light of various wavelengths are reported. The experiments indicate that neither tachysterol~2~ nor ergosterol are primary reaction products of lumisterol~2~. Lumisterol~2~ is exclusively converted into pre‐ergocalciferol. The quantum yield of this reaction is 0.41 at 2537 Å.

## Abstract The quantum yields of the isomerizations of pre‐ergocalciferol and tachysterol~2~ in ether at 20° under the influence of ultraviolet light of 2537 Å were found to be 0.49 and 0.11 respectively. Ergosterol is not formed from tachysterol~2~ during irradiation but originates exclusively fr
