Photochemical Reactions in the Gaseous, Liquid and Solid States

Abstract

“PHOTOCHEMISTRY is concerned with processes” in which light quanta are absorbed and chemical changes result. A molecular species is characterized by a certain spatial arrangement of atoms governed by forces due to electrons. The oscillating electric field of a light quantum acts on a binding electron and raises it to an energy-level where the bond is either loosened or broken. This permits the spatial rearrangements to take place which we observe as chemical change.
