Abstract
An investigation has been made of the photolysis of liquid acetone in the temperature range from 55° to −25 °C. The quantum yields of all products are small, and decrease strongly with decreasing temperature. It is concluded that the low yields can be explained both on the basis of the 'cage effect', and by the deactivation of an excited molecule. At high temperatures and intensities the gaseous products can be accounted for on the assumption that radicals have escaped from the 'cage' and react analogously to the gas-phase mechanism. At low temperatures ethane formation in the 'cage' may be of importance.Keywords
