Abstract
The photolysis of acetone in various solutions has been investigated by analysis of reaction products as well as absorption spectroscopy. The rate of photolysis of acetone in aqueous solution decreases on addition of methanol or with increasing concentration of acetone, being much higher than that in methanol and heptane solutions. The results suggest that intermolecular hydrogen abstraction plays a significant role in quenching of triplet acetone. This is supported by spectroscopic studies which reveal formation of the enol form of acetone as an intermediate in the decay process of triplet acetone.Keywords
