Abstract

The parameters of NH2D in the ground and ν2 states have been refined by a simultaneous analysis of the microwave, FTIR, and diode laser data. The intensities of 46 NH2D lines have been measured, and from a least-squares fit of the intensity data the a ← s, s ← a, s ← s, and a ← a transition moments have been derived. The intensities of the lines in the ν2 band of NH2D have been calculated taking into account the inversion-rotation interaction. The accuracies of the wavenumbers and intensities calculated with the new parameters are estimated to be better than ±0.0002 cm-1 and ±5%, respectively. The matrix elements for interaction of vibrations through x, y, and z axis couplings are appended.
