Isotopic effects in rotational de-excitation of H2CO isotopologues (HDCO and D2CO) by He at low temperatures
Context. In typical interstellar molecular clouds, densities are low; therefore, the analysis of observed molecular spectra requires using non-LTE models. Critical inputs for these models are collisional rate coefficients of the detected molecule with He and H2. For formaldehyde (H2CO), such data ar...
