title: PHOTOCHEMISTRY OF VISUAL PURPLE : I. THE KINETICS OF THE DECOMPOSITION OF VISUAL PURPLE BY LIGHT.
abstract: 1. Visual purple solutions are prepared under such conditions that the bleaching reaction is irreversible. 2. A method is described for the colorimetric estimation of very small quantities of visual purple. By this means the kinetics of the bleaching reaction are investigated. 3. The results show that the course of the decomposition follows that of a monomolecular reaction, without any measurable period of induction or after effect.
