Abstract
Laser-induced fluorencence excitation spectrum of B←X(l-0) transition of C2 anions producing from discharging with the CH4/Ar mixture under the supersonic jet was reported. The rotational spectrum was assigned, furthermore rotational constants of X and B states were determined. In addition, the lifetime measurement for the B(v = 1) state was carried out and the lifetime obtained is 80±1 ns.
