The high-resolution Fourier transform spectra of the D2O molecule have been recorded and assigned in the 4200-5700 cm-1 region where the vibration-rotation bands 2ν1, 2ν3, ν1 + ν3, ν1 + 2ν2, 2ν2 + ν3, and 4ν2 are located. The presence of numerous and very strong accidental perturbations between the states of the hexad makes it necessary to take into account not only ordinary resonance interactions of the Fermi, Darling-Dennison, and/or Coriolis types, but interactions between the states (ν1ν2ν3) and (ν1 ∓ 2ν2 ± 2ν3 ± 1) as well. Parameters of all six vibrational states of the hexad were obtained from the fit of experimental energy values.
