Rotational spectra have been observed for ten isotopic species of KrHCN using the pulsed Fabry-Perot Fourier transorm technique.The 83Kr nuclear quadrupole coupling constant has been measured in 83KrHC14N, 83KrHC15N, and 83KrDC14N.Values of the rotational constants B0, centrifugal distortion constants DJ and H, 14N and 83Kr nuclear quadrupole coupling constants are:
. aCalculated using DJ=47.401 kHz, H=69.4 Hz. bCalculated using DJ=40.350 kHz, H=54.3 Hz. cCalculated using DJ=26.973 kHz, H=27.2 Hz.These constants are consistent with a linear or near-linear configuration, with a Kr-HCN center-off-mass separation of 4.54 Angstroem, and the Kr atom located 27 deg off the HCN figure axis on average, where the vertex of this angle is placed on the HCN center-off-mass.KrHCN exhibits unusually large centrifugal distortion in comparison to previously studied Kr-hydrogen halide systems.We find that the measured 83Kr nuclear quadrupole coupling constants in 83KrHC14N and 83KrDC14N are consistent with a long range polarization model previously used to explain values of χKr in KrH(D)Cl and KrH(D)F.
