text: The primary process of photochemistry includes the absorption of a photon by a molecule that activates (excites) the molecule, which in turn will lose its energy in different ways, i.e., by heat, by fluorescence or phosphorescence, by chemical changes within the molecule, by breaking of chemical bonds (photolytic cleavage), or by transferring its energy to another atom or molecule.
