Abstract

An absorption at 2308.6cm−1 has been assigned to the ν2, antisymmetric CCCO stretching mode of HCCCO which was produced by trapping in Ar the products of the vacuum ultraviolet (VUV) photolysis of a mixture of acetylene and carbon monoxide in a Fourier transform infrared study. The assignment is confirmed by measurements for a variety of D−,18O−, and 13C− substituted isotopomers. This is the first identification of a fundamental vibration of the HCCCO radical.
