摘要：

Dispersed fluorescence (DF) spectra of the calcium ethoxide radical (CaOC2H5) have been obtained by pumping the (A) over tilde (2)(1)A'<-(X) over tilde (2)A' and the (A) over tilde (2)(2)A '' <- (X) over tilde (2)A' origin bands in its laser-Xinduced fluorescence spectrum. Dominant transitions in the vibrationally resolved DF spectra are well reproduced using Franck Condon factors predicted by complete active space self-Xconsistent field (CASSCF) calculations. Collision-Xinduced population transfer between the (A) over bar (2)(1)A' and the A(2)(2)A '' states results in additional peaks in the experimental DF spectra. Differences between the intensities of vibronic bands in the (A) over tilde (2)(1)A'-> (X) over tilde (2)A' and the (A) over tilde (2)(2)A '' <-(X) over tilde (2)A' DF spectra are attributed to different symmetries of the two excited electronic states.
