✦ Synopsis

New laser induced fluorescence spectroscopic transitions of the vinoxy (CH2CHO) radical have been observed and assigned in the 310-330 nm wavelength region fluorescence. Both excitation and emission spectra have been recorded. In the excitation spectrum, the peaks at 30211, 30381 and 30637 cm -1 have been assigned to the 6~, 5~ and 4~ vibronic transitions of the 132,~'-Y(2~ ' manifold. The assignments are 1376, 1565 and 1553 cm-~ for the v 6, v 5 and v 4 vibrational modes, respectively in the ground electronic state, and 1413, 1583 and 1634 cm-], respectively in the excited state.
