We present the gas phase spectrum of singly deuterated hydrogen peroxide, HOOD, in its vibrational ground state, recorded by the high resolution Fourier-transform interferometer located at the AILES synchrotron beamline connected to SOLEIL. More than 1000 transitions in the range from 20 to 143Â cmâ1 were assigned, leading to a set of preliminary rotational and centrifugal distortion constants determined by least squares fit analysis. All transitions are split by the tunneling motion of a hindered internal rotation. The splitting has been determined to be 5.786(13)Â cmâ1 in the torsional ground state and it shows a dependence on the rotational quantum number Ka. Some perturbations were not treated yet, but the present analysis permits to obtain a preliminary set of parameters.
⺠We present the gas phase spectrum of HOOD in its vibrational ground state. ⺠The spectrum was measured with a FT-spectrometer at the AILES beamline of synchrotron SOLEIL. ⺠On the basis of these data we derived rotational constants and the size of the torsional splitting.
