摘要：

We report the laser excitation and dispersed fluorescence spectra of the (A) over tilde(2)E <-- (X) over tilde(2)A(1) transition of the jet-cooled MgCH3, radical. Improvements to the experiment have allowed the observation of 6(0)(1) and 2(0)(1) vibronic features not previously observed. Analyses of these bands, along with the previously reported 0(0)(0) spectra, yield the rotational constants and values of the Coriolis and the spin-orbit coupling constants for the radical's (A) over tilde(2)E state. We also are able to rather completely characterize a small, dynamic Jahn-Teller effect. The dispersed fluorescence spectrum was analyzed and all observed (X) over tilde(2)A(1) state vibrational features were assigned. (C) 1999 Academic Press.
