The molecular Zeeman spectra of LiH and LiD in the ¹Σ ground electronic state have been measured in the first rotational state (J=1) and zeroth vibrational state (v=0) by molecular beam electronic resonance. By fitting the observed resonance lines of several different magnetic fields to an appropriate Hamiltonian, values for the rotational g factor (g_J), the anisotropies of the nuclear shieldings (sigma_T,sigma_T), and the anisotropy of the molecular magnetic susceptibility (xi_T) were measured. In order to fit the observed magnetic field spectra, accurate values of the hyperfine constants were required. The hyperfine spectra of several (J, v) states of LiH and LiD were measured.
