Abstract
THE rapid development of molecular physics during the last twenty years has stimulated interest in photochemical processes, which are now being studied with renewed vigour. No little advance is to be recorded in this domain in interpreting the mechanism of photochemical action in terms of the Stark-Einstein law of quantum excitation, the conception of both molecules and atoms in excited states and of collisions of the second kind. Whilst from many points of view the physical processes occurring in gases or liquids when subjected to radiation of wave-lengths lying within a band of their absorption spectrum are obscure and the mathematical formulation still in a state of flux, yet in many directions we may trace the influence of these investigations in rendering the subject of photochemistry more precise and quantitative.
