Abstract

High-resolution rotational spectra of C5H558Nil4N16O were obtained with a Flygare-Balle type pulsed-beam microwave spectrometer. Quadrupole hyperfine structure was clearly resolved for J = 1 → 2, 2 → 3, 3→ 4, and 4 → 5 transitions involving K = 0, 1, 2, 3, and 4 states. A nitrogen quadrupole coupling strength of eqQ = —1.216 (11) MHz and rotational constant B = 1259.2743 (8) MHz were obtained by fitting the observed spectra. DJKand Dj were also obtained from fitting the spectra. This appears to be the first gas-phase, microwave measurement of nitrogen quadrupole coupling in a transition-metal complex. The quadrupole coupling strength is compared with values for other molecules and complexes containing the NO group.
