Using a UFS–02 Fourier–transform spectrometer the absorption spectrum for the isotope–substituted modification of water vapor HD16O has been recorded in the region 5087–5279 cm-1 with spectral resolution 0.0098 cm-1 and accuracy in the determination of line positions better than 0.005 cm-1. 103 lines of the band formed by the transition to the vibrational state (011) have been interpreted, and 72 energy levels up to J ≤ 11 and Ka ≤ 6 have been deduced. A set of rotational and centrifugal constants reproducing the experimental data with a mean accuracy of 0.0034 cm-1 has been reconstructed from this spectrum.
