The Role of the Excited State in Organic Photochemistry
- 160 Downloads
Organic photochemical reactivity, along with organometallic reactivity, poses currently perhaps the most exciting challenge to those interested in theoretical organic chemistry. Because of their inherently more complicated nature, photochemical reactions are very difficult to analyze experimentally to the degree of mechanistic detail to which one has become accustomed in the case of thermal reactions. Even relatively crude theory is thus offered a good chance to make fundamental contributions to the understanding and prediction of the events occurring between initial excitation of an organic molecule to an electronically excited state (S, singlet; T, triplet) and the emergence of the first product in its thermalized ground state (S0).
