Pure ethyl acetate was subjected to electron pulse radiolysis in the liquid state and the absorption spectrum of the transient species produced was obtained between 280 and 650 nm. Two different species were produced, one with a short life of about 150 ns absorbing at longer wavelengths attributed to the solvated electron and a much longer lived radical absorbing at wavelengths less than 400 nm. The solute triplet yields were followed using anthracene and biphenyl at different concentrations. An upperlimit for the yield of excited singlet anthracene was estimated from the study of fluorescence to be G approximately equal to 0.1. Anthracene singlet yields in the presence of benzene at different concentrations were measured and the contribution of ethyl acetate positive ions in forming the additional exicted singlets is discussed. The free ion yield is G = 0.25. Yield of ethyl acetate positive ions scavengeable at high benzene concentrations is G = 0.63.
