VizieR Online Data Catalog: Rest frequencies of ketenyl (HCCO and DCCO) (Chantzos+, 2019)
Abstract
In the present work, the rotational spectra were taken with the frequency-modulation mm/sub-mm Absorption Cell spectrometer developed at the Center for Astrochemical Studies (CASAC) in Garching.
iWe made a rotational analysis of the ketenyl radical HCCO and its deuterated counterpart DCCO. For each isotopolog we measured and assigned more than 100 lines. We extended the measurements up to ~650 GHz, which helped us improve the determination of the spectroscopic parameters with respect to the previous study by Endo & Hirota (1987, J. Chem. Phys., 86, 4319). In particular, we measured the rotational transitions with N ranging from 8 to 27 for HCCO and with N=9-33 for DCCO with a maximum Ka of 4. (2 data files).- Publication:
