Gas-phase electron paramagnetic resonance spectrum and dipole moment of NF(1∆)

Abstract

Abstract The gas-phase paramagnetic resonance spectrum of NF in the J = 2 rotational level of the 1∆ state has been studied, and the dipole moment in this state is found to be 0.37 ± 0.60D. The rotational constant previously determined from the electronic spectrum is shown to be consistent with the electron resonance results, and the 14N quadrupole coupling constant e2qQ is 4.1 ± 0.2 MHz. The hyperfine coupling constants of the 14N and 19F nuclei are + 109.92 ± 0.14 and +758.06 ± 0.23 MHz respectively.
