EPR OBSERVATION OF STEADY-STATE ETHYL RADICAL CONCENTRATION IN RADIOLYSIS OF LIQUID ETHANE
Journal Article
·
· Journal of Chemical Physics (U.S.)
EPR observations of radicals produced during photolysis and radiolysis have been reported but the second-order rate constants used were considerably less than steady-state. The present study is focused on the steady-state concentration of reactive radicals produced in liquid systems. The EPR spectrum of liquid ethane was examined during irradiation of the sample with 2.5-Mev electrons. The spacing and intensity of the lines indicate that the electron is coupled to one of two groups of equivalert protons and a second group of three equivalent protons. The resulting spectrum consists of four sets of triplets. The secondorder rate constant for the recombination of ethyl radicals in ethane is estimated to be 4 x 10/sup 9/ liters mole/sup -1/ sec/sup -1/. (B.O.G.)
