We report a study of the {ital C} {sup 3}{Pi}--{ital X} {sup 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 {ital v}{prime}=0--8 of the {ital C} state and for {ital v}{double prime}=0--5 of the {ital X} state. The spectroscopic constants for the {ital C} state are {ital T}{sub {ital e}}=22 830.4(9) cm{sup {minus}1}, {omega}{sub {ital e}}=615.7(8) cm{sup {minus}1}, and {ital r}{sub {ital e}}=1.919(3) A; for the {ital X} state, {omega}{sub {ital e}}=965.16(24) cm{sup {minus}1} and {ital r}{sub {ital e}}=1.7182(2) A.
