Abstract

Hyperfine structure on the 4₁₄-4₀₄ rotation-inversion transition in NH₂D was measured with a twocavity maser spectrometer with 350-Hz linewidth. A reasonably good fit to the observed transitions is obtained by including the nitrogen quadrupole interaction, the nitrogen spin-rotation interaction, the deuteron quadrupole interaction, the deuteron spin-rotation interaction, and the nitrogen-deuteron spinspin interaction in the Hamiltonian. The values of the coupling constants obtained are: for the 4u state (e_qJQ)N=-1895.65±0.7 kHz, (e_qJQ) _D=-75.78±0.7 kHz, and for the 4 state (e_qJQ)N=- 1811.55± 0.7 kHz, (e_qjQ)i3= -80.13±0.7 kHz, and for the values of the other parameters averaged over these states CN = 5.027±0.18 kHz, CD=- 2.33±0.18 kHz, and D_ND=0. 307±0.70 kHz. The rotation-inversion frequency for this transition is 25 023 794.706±0.07 kHz.
