The high-resolution Fourier transform spectrum of the D2O molecule was recorded in the 3200-4200 cm-1 region, where the bands of the second triad of interacting vibrational states are located. As a result of the theoretical analysis, both the rotational-vibrational structure of the (Oil) vibrational state was improved, and the rotational energies of the (110) and (030) vibrational states were determined for the first time up to rotational quantum numbers Jmax. = 15 and 14, respectively.
