Evidence for electron spin-torsion coupling in the rotational spectrum of the CHCO radical
Laurent H. Coudert, Olivier Pirali, Marie-Aline Martin-Drumel +4
Open-shell non-rigid molecular systems exhibiting an internal rotation are likely candidates for a coupling between the spin angular momentum of the unpaired electron and the torsi…

The rotation-tunneling spectrum of 3-hydroxypropenal and confirmation of its detection toward IRAS 162932422 B
H. S. P. Müller, A. Coutens, J. K. Jørgensen +3
3-Hydroxypropenal (HOCHCHCHO) is the lower energy tautomer of malonaldehyde which displays a complex rotation-tunneling spectrum. It was detected tentatively toward the solar-type…
