Abstract: 

The vinoxy, CH2CHO, free radical has been produced in a supersonic free jet expansion by ArF excimer laser photolysis of a suitable precursor like ethyl vinyl ether. Electronic spectra involving the math B2A″ ↔ math X2A″ transition have been observed at vinoxy temperatures between 2–30 K. Rotational structure as well as spin splittings have been resolved. Analysis of the spectrum yields the electronic term value, vibrational frequencies, rotational and spin‐splitting constants for both electronic states. These molecular parameters provide considerable information about the electronic and geometric structure of the radical.
