✦ Synopsis

Dichlorosilylene, Sic12 , in the gas phase has been detected by laser-induced fluorescence of the x 'B1-?? 'Al transition in the 309-333 mn region. The wavenumber of the 0: transition is determined to be 30003.6 f 0.5 cm-' (333.20 nm). The fundamental vibrational frequencies are assigned to be IJ~ = 526.5 cm-', v; = 201.2 cm-' (% 'Al), vi = 435 f 5 cm-', and ui = 149.9 * 0.5 cm-l (x 'B1). The collision-free radiative lifetime of the 'E$ state is 77 * 3 ns at uh =7 (321.949 m).

In the spectral range 34500-40000 cm-1, two molecular species were detected by means of laser-induced fluorescence in the 193 nm photolysis of acetylene: one is C2(a 3Hu), the other is most likely C2H(X). The identification of C2H is based upon the rotational constants (B"= 1.4397-1.4534 cm-t), the
