Radiolysis of Ethane-1,1,1-d3

Abstract
The radiolysis of CH3CD3 has been investigated with particular emphasis on the effect of pressure, temperature, and addition of xenon on the molecular hydrogen formation. The hydrogen formed by molecular detachment was determined by irradiating CH3CD3 in the presence of C2H4, NO, O2, or I2. The formation of molecular hydrogen in the unimolecular decomposition of the parent ion and in the decomposition of the neutral excited ethane molecule are considered. Methane formed in the presence of scavengers may be attributed to an ion‐molecule reaction or to an intramolecular process similar to that proposed in the direct photolysis of ethane. Evidence is presented for occurrence of a reaction producing ethylene in addition to the one in which molecular hydrogen accompanies the formation of ethylene.
