The rotational spectral lines of the13C isotopic species of CCS (13CCS, C13CS, and13C13CS) have been observed using a Fourier transform microwave spectrometer in combination with a pulsed-discharge nozzle. The hyperfine-resolvedJN= 10-01,JN= 21-10, andJN= 32-21transitions have been observed in the 11-, 22-, and 33-GHz regions, respectively, with an accuracy of about 5 kHz. The observed transition frequencies for13CCS and C13CS are analyzed simultaneously with millimeter-wave data, and the hyperfine interaction constants for both species are determined accurately. Astronomical implications for these radicals are discussed.
