摘　　要：由CH4/Ar放电产生C2负离子,在超声射流条件下,观测到B←X(1-0)跃迁的激光诱导荧光激发谱。对该谱带的转动结构进行了标识,并得到X(v=0)和B(v=1)态的转动常数。另外测量了B(v=1)振动态的寿命,其寿命为80±1 ns。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? ns.
