摘要：

We report a study of the C 3-PI-X 3-PI band system of the SiC radical. Jet-cooled SiC is produced by a laser vaporization/pulsed beam source and is probed by pulsed laser-induced fluorescence excitation spectroscopy. Vibrational term energies and rotational constants are determined for upsilon' = 0-8 of the C state and for upsilon" = 0-5 of the X state. The spectroscopic constants for the C state are T(e) = 22 830.4(9) cm-1, omega-e = 615.7(8) cm-1, and r(e) = 1.919(3) angstrom; for the X state, omega-e = 965.16(24) cm-1 and r(e) = 1.7182(2) angstrom.
