High-resolution diode laser spectra and medium-resolution F-T spectra of deuterated ammonia have been obtained in the 700- to 1030-cm-1 region. Out of about 800 lines measured by diode laser spectroscopy, approximately 500 lines have been assigned to the ν2 transitions of NH2D. The parameters for the ground and ν2 states of NH2D have been derived by the simultaneous analysis of the infrared and microwave data. The standard deviation for the IR data is ~8 × 10-4 cm-1. It is shown that the energy levels of NH2D in the ν2 state are heavily perturbed by inversion-rotation interaction and that it is necessary to include higher order inversion-rotation interaction terms to obtain a satisfactory fit of the observed data.
