摘要：

The high resolution infrared spectrum of the heavy atom antisymmetric stretch of the ketenyl radical (HCCO) has been observed by means of infrared kinetic spectroscopy producing the ketenyl by 193 nm photolysis of ketene with diode laser probing of the transient absorption. Individual rovibrational transitions have been identified near the band origin located at approximately 2023 cm-1. A preliminary kinetic study of the ketenyl radical's reaction with nitric oxide was conducted. A second order rate constant of 3.9(5) x 10(-11) cm3 molecule-1 s-1 was obtained for this reaction by following the decay of ketenyl in the presence of excess NO.
