The photoelectric interaction in which the photon transfers its energy to the electron is the first step. Photochemistry is a branch within the field of chemistry which is focused on the study of chemical reactions which involve light, either because light acts as a catalyst for reactions, or because reactions produce light. Photochemistry is concerned with the absorption, excitation and emission of photons by atoms, atomic ions, molecules, molecular ions, etc. The low light penetration makes it difficult to drive reactions to completion and attempts to do so often result in over-irradiation of the solution close to the light. ^ The excited state properties of these compounds are now fairly well understood. in CONTENTS Difference between Thermal and Photochemical Reactions Absorption of Radiation Absorption Spectrum Laws of Photochemistry Behavior of the Excited State Molecules Efficiency or Quantum Yield.
