photochemistry : photochemistry photochemistry is the study of the interaction of electromagnetic radiation with matter resulting into a physical change or into a chemical reaction . Organisms that obtain their nutrients by breaking down wastes and dead matter. Photochemistry -chemical reactions initiated by light -energy is absorbed or emitted by matter in discrete quanta called photons -absorption of light leads to an electronic excitation (ground state→excited state) -promote an e-like n→π∗or π→π∗ -most chemistry takes place from S1and T1excited states No public clipboards found for this slide.
