    • Abstract

       

      In the flash-photolysis of oxazole and isoxazole, new transient absorption bands are observed in the region 3080–3670 A. Vibrational analysis of these bands showed that they can be arranged into two electronic systems with their origin bands at 3333.60 A and 3367.01 A. Based on the experimental conditions under which the bands are produced and on the analysis of their vibrational and gross-rotational structure, these bands are assigned to a new carrier, the HCCO free radical.
