Abstract

The pure rotational spectrum of (MgNC)-Mg-24-N-14-C-12, between 11.9 and 23.9 GHz, has been measured using a pulsed jet Fourier transform microwave spectrometer. The hyperfine structure due to the N-14 nucleus has been measured, and the nuclear quadrupole coupling, Fermi contact, and dipole-dipole interaction constants have been determined. The ionic character of the metal-isocyanide bond has been investigated through the nuclear quadrupole and magnetic hyperfine parameters. (C) 1998 Academic Press.
