✦ Synopsis

The microwave spectra of fluorocyanobutadiyne, FCSN, in the ground, v,, (skeletal bending) and 2vll states were observed with a source-modulated spectrometer. The FCsN molecule was generated in a free space absorption cell by a dc glow discharge in pentafluorobenzonitrile, C6FsCN. The rotational and centrifugal distortion constants for the ground state were determined to be 755.398325(41) MHz and 8.3458( 11) Hz, respectively. The /-type doubling constant for the v,, state, 0.508887(48) MHz, was consistent with the value calculated from the harmonic force field.

The millimeter-wave spectrum of HCCCCF was observed in the ground state as well as in the low-lying vibrationally excited states nu7, nu8, nu9 and also associated nu8 + nu9, 2nu9, and 3nu9 states. The HCCCCF molecule was produced by a dc glow discharge in a flowing vapor of 2,3,4,5,6-pentafluorostyr
