Abstract
The identification of a fundamental vibration of the HCCCO radical has been made in a Fourier transform infrared (FTIR) study involving exte nsive isotopic measurements. An absorption at 2308.6 cm-1 has been ass igned to the nu2, antisymmetric CCCO stretching mode of HCCCO which wa s produced by trapping in Ar the products of the vacuum ultraviolet (V UV) photolysis of a mixture of acetylene and carbon monoxide. The assi gnment is confirmed by measurements for a variety of D-, O-18, and C-1 3-substituted isotopomers.
