摘要：

Rotational spectra of a transient molecule, CCCS, and its isotopic species, 13CCCS, C13CCS, and CCC34S, have been observed by using a Fabry-Perot-type Fourier-transform microwave spectrometer combined with a pulsed discharge nozzle. C3S has been produced by a discharge of a mixture of CS2 and C2H2 diluted in Ar, and subsequently cooled to a few kelvin in a supersonic expansion. From the determined rotational constants for the four isotopic species, the following substitution structure has been derived: rs(C1C2) = 1.2724, rs(C2C3) = 1.3028, and rs(C3S4) = 1.5323 A ̊. The possibility of applying the present experimental setup to studies of other transient species and free radicals is briefly discussed. © 1992.
