摘要: Zeeman effects in the absorption spectra of formaldehyde H 2 CO, HDCO, and D CO were studied microwave region with magnetic field 1500∼300 oersteds. The effective g -values several rotational states elements -tensor a , b c these molecules determined. Dependences on quantum numbers J τ consistent among isotopically substituted molecules. components -tensors have been found to be =2.86±0.04 for 2.00±0.05 1.46±0.05 CO. They are extraordinarily large compared those other already known. A brief qualitative interpretation is given.
