The vibration-rotation spectrum of HDO in the 2400-3300-cm-1 region has been studied at 0.01-cm-1 resolution with a Fourier transform spectrometer. Values of the ground state levels and levels in the (100) and (020) states have been determined from the data. The ground state levels are fitted to a Watson-type Ham-iltonian from which 17 rotational constants are obtained. Measurements of the strengths of over 1100 lines have been made using a nonlinear least-squares fitting technique, and 548 of these lines are analyzed to determine the band strengths, the coefficients of the F factors, and the Coriolis interaction parameters. The strengths of the A- and B-type (100) bands and the A- and B-type (020) bands are 53.2 ± 0.9, 0.43 0.07, 6.00 ± 0.54, and 2.75 ±0.12 cm-2 atm-1 at 296 K, respectively.
