The direct and sensitized irradiations of the βγ-unsaturated ketones1(a-c) and2 have been investigated.1a,1c and2, on direct irradiation give rise to ODPM rearrangement in addition to the expected [1,3]-acyl represent the first examples of ODPM rearrangements arising from some state other than T 1 (π-π *). [1,3]-Acyl shifts observed in the sensitized reactions can involve Cited by: Mechanistic organic photochemistry is the aspect of organic photochemistry which seeks to explain the mechanisms of organic photochemical reactions. The absorption of ultraviolet light by organic molecules often leads to reactions. In the earliest days, sunlight was employed, while in more modern times ultraviolet lamps are employed. Room-temperature irradiation of 4,4-diphenyl- and 4-methylphenyl-cyclopentenone led very efficiently to keten rearrangement products [e.g.(4)] rather than bicyclic ketones [e.g.(6)] characteristic of cyclohexenone photochemistry; at low temperatures the bicyclic ketone primary product underwent further photochemical reaction to give the keten, but the bicyclic ketone was not an intermediate Cited by: 1.

Journal of the American Chemical Society George Hamilton, Hugo Sanabria, in Spectroscopy and Dynamics of Single Molecules, Quantum yield. The quantum yield of a de-excitation process refers to the efficiency ratio of events corresponding to that process with respect to the total number of excitation events, or, equivalently, the probability of each type of de-excitation event. Thus, the quantum yield for fluorescence is.
