Fourier transform microwave spectrum of HCCC15N and global analysis of the high resolution infrared and rotational spectra up to 1700 cm−1

The rotational spectrum of an enriched sample of HCC-C15N was measured in the range 8-27 GHz by means of a waveguide Fourier transform microwave spectrometer. New transitions were also measured in the millimetre- and submillimetre ranges. These measurements combined with the available rovibrational and rotational data [Fayt et al., J. Mol. Struct. 695-696 (2004) 295], with many newly assigned infrared bands, were used for a global rovibrational analysis of all vibrational states up to 1700 cm−1. A full set of 243 molecular parameters for the modes v4-v7 has been deduced.
