Zeeman Effect in the 1- to 3-Millimeter Wave Region: Molecular g Factors of Several Light Molecules

Abstract

The Zeeman effect has been observed in the microwave rotational spectra of several light molecules, and the high‐frequency limit of such measurements has been extended for the first time to 1.1 mm wavelength. The magnitudes of the molecular g factors g_J and, where applicable, the components of the g tensor lying along the principal axes of rotation, have been obtained for DBr, DI, CO, PH₃, PD₃, SO₂, O₃, H₂S, HDS, and D₂S. When combined with information from other sources the data have permitted, in addition, a determination of the sign of g_J for DBr and DI, and of the sign of the electric dipole moment of DI.
