Abstract
The $C_{2}H_{3}$ vinyl radical, which was first observed spectroscopically by $ESR^{1}$ in matrices, has been found to be one of the products of the vacuum UV photolysis of acetylene trapped in argon at $10 K,2$ and may also be formed from ethylene. The results of an FTIR investigation of the mid-infrared spectrum of $C_{2}H_{3}$ using deuterium and carbon-13 isotopic substitution will be discussed, and compared with the predictions of recent ab initio $calculations^{3}$.
