We present a computational model for Zeeman splitting of the 6s ^2[3/2]^10->6p ^2[5/2]2 absorption of neutral xenon at 834.682 nm (air). The model accounts for Zeeman splitting of the xenon hyperfine structure by assuming that the extra-nuclear spin and spin-orbit wavefunctions are separable for an atomic system described by a rigid spherical spinning body in a central force field, all immersed in a magnetic field. This theoretical approach  permits calculation of the intensity and displacement of Zeeman-shifted hyperfine lines for σ and π beam polarizations. By comparing the resulting model with previously-reported Zeeman-split optogalvanic spectra , we explore the utility of Zeeman splitting of laser-induced fluorescence spectra as a magnetic component intensity diagnostic in xenon electrostatic thruster plumes.
