Rl. Wan et al., OBSERVATION OF NEW VIBRONIC TRANSITIONS IN THE (B)OVER-TILDE(2)A''-(X)OVER-TILDE(2)A'' MANIFOLD OF THE CH2CHO RADICAL, Chemical physics letters, 260(5-6), 1996, pp. 539-544
New laser induced fluorescence spectroscopic transitions of the vinery
(CH2CHO) radical have been observed and assigned in the 310-330 nm wa
velength region fluorescence. Both excitation and emission spectra hav
e been recorded. In the excitation spectrum, the peaks at 30211, 30381
and 30637 cm(-1) have been assigned to the 6(0)(1), 5(0)(1) and 4(0)(
1) vibronic transitions of the (B) over tilde(2)A''-(X) over tilde(2)A
'' manifold. The assignments are 1376, 1565 and 1553 cm(-1) for the nu
(6), nu(5) and nu(4) vibrational modes, respectively in the ground ele
ctronic state, and 1413, 1583 and 1634 cm(-1), respectively in the exc
ited state.
