Abstract

The C2H3 vinyl radical, which was first observed spectroscopically by ESR1 in matrices, has been found to be one of the products of the vacuum UV photolysis of acetylene trapped in argon at 10K,2 and may also be formed from ethylene. The results of an FTIR investigation of the mid-infrared spectrum of C2H3 using deuterium and carbon-13 isotopic substitution will be discussed, and compared with the predictions of recent ab initio calculations3.
