VizieR Online Data Catalog: The mm and sub-mm spectra of 13C-glycolaldehydes (Haykal+, 2013)
Abstract
To allow the detection of the 13C-isotopologues of glycolaldeh the interstellar medium, their rotational spectra in the millimeter and submillimeter-wave regions were studied. The spectra of 13CH2OHCHO and CH2OH13CHO were recorded in the 150-945GHz spectral range in the laboratory using a solid-state submillimeter-wave spectrometer in Lille. The observed line frequencies were measured with accuracy, better than 30kHz up to 700GHz and 50kHz above. The analysis was performed using a standard Watson Hamiltonian. Around 10000 new lines were identified for each isotopologue. The spectroscopic parameters were determined for the ground and the three lowest vibrational states, respectively up to 945 and 630GHz. Previous microwave assignments of 13CH2OHCHO were not confirmed. The provided line-lists and sets of molecular parameters meet the needs for a first astrophysical search of 13C-glycolaldehydes.
