The pure rotational spectra of the astrophysically important monosubstituted HC3N-isotopomers HCC13CN , HC13CCN , H13CCCN , and HCCC15N in their ground and various vibrationally excited states, which will be denoted (v4, v5, v6, v7) hereafter, have been studied extensively in the 2 mm region. Transitions of the ground vibrational states and vibrational satellites appendant to the two lowest bending fundamentals nu6 and nu7 have been measured up to 625 GHz. The Fermi resonance system (0,1,0,0)/(0,0,0,3) has been analyzed for the HCC13CN and H13CCCN isotopomers for the first time. Furthermore, pure rotational transitions of the four doubly substituted isotopomers HC13C13CN, H13CC13CN, H13C13CCN, and HCC13C15N could be detected for the first time, not only in the ground but also in vibrationally excited states. This work is to provide accurate frequency predictions for the astronomical community.
