Abstract

Seven a-dipole and seven b-dipole transitions were measured for one isomer of the NNO-HCN complex using a pulsed-beam, Fourier transform microwave spectrometer. Rotational constants A+ΔK=10326.3(4) MHz, B=2814.32(14) MHz and C=2201.00(12) MHz and distortion constants ΔJ=0.014(8) MHz and ΔJK=0.14(6) MHz were obtained by fitting the observed transition frequencies. A quadrupole coupling strength due to the HCN nitrogen of eQqaa=1.97±0.05 MHz was obtained by fitting low-J transitions. Approximate structural parameters are obtained using moments of inertia and quadrupole coupling data.
