Intermediates Produced in the Flash Photolysis of Acetone and Amides in Aqueous Solution

Authors: M. Nakashima, E. Hayon The flash photolysis of air-free aqueous acetone solutions was shown to produce CH2COCH3 and (CHg^COH radicals. The acetonyl CH2COCH3 radical has an absorption maximum at 295 nm and an extinction coef- ficient 6295 = 800 ± 150 M-1 cm-1. No intermediates could be observed in the flash photolysis of air-free aqueous amide solutions. In presence…
