Thaddeus, P., L.C. Krisher, and P. Cahill, 1964: Hyperfine structure in the microwave spectrum of NH2D. J. Chem. Phys., 41, 1542-1547, doi:10.1063/1.1726119.
Hyperfine structure in the 313 → 303 rotation-inversion transition of deuterated ammonia NH2D at 18 807.7 Mc/sec has been studied with a beam maser microwave spectrometer giving a linewidth of 7 kc/sec. All details of the observed hyperfine structure have been accounted for in terms of the various quadrupole, spin-rotation, and spin-spin interactions of the four coupling nuclei. The hyperfine coupling constants which have been determined with the aid of a digital electronic computer are, for the 313 state: (eqJQ)D = -62.5±1.0 kc/sec, CD = -2.7±0.3 kc/sec, CH = -13.6±0.5 kc/sec; and for the 303 state: (eqJQ)D = -73.9±1.0 kc/sec, CD = -2.7±0.3 kc/sec, CH = -12.3±0.5 kc/sec. On the assumption that the electric field at the deuteron is cylindrically symmetric about the N-D bond direction ξ, we find that (eVξξQ)D = 282±12 kc/sec, or Vξξ = 1.38±0.06×1015 statV/cm2, where Vξξ is the second derivative of the electrostatic potential along ξ.
