| Abstract: | The 2ν2 and ν1 bands of HDO lying in the region 2235–3115 cm?1 were analyzed using Fourier transform spectra of “pure” D2O and of H2OD2O mixtures. From this analysis, an extended and precise set of rotational levels belonging to the (000), (020), and (100) vibrational states was derived. Using the (000) levels together with the existing microwave data as input in a least-squares fit, it was possible to obtain reliable rotational constants for the ground state of the HDO molecule. |
