High-resolution rotational analysis of deuterated hypochlorous acid: Ground state, (100), and (020) vibrational states

The high-resolution Fourier transform spectra of the DOCl molecule were rec orded and analyzed in the region of the v, and 2 nu (2) bands. Transitions belonging to the nu, and 2 nu (2) bands were assigned up to J(max) = 55 and 46, respectively. The sets of spectroscopic parameters of the (100) and (0 20) vibrational states obtained from the fit reproduce their energies deriv ed from the experimental data with accuracies close to experimental uncerta inties.
