✦ Synopsis

It is shown that the magnetic field effect permits to unambiguously determine the nature of the fine structure lines of the fluorescent level 4 T 1 of a d 5 ion coupled to e-vibrational modes. Polarized excitation spectra of the fluorescent 4 T 1 level of Mn 2 in pure cubic ZnS have been obtained up to 5 T by using polarization modulated laser spectroscopy performed at 1.9 and 4.2 K for B k001k k and B k111k k. The energies and relative dipole strengths (RDS) of the Zeeman transitions between the fundamental and the excited states, are correctly described by Ham's phenomenological model for orbital triplet states and the Zeeman Hamiltonian m B g e S Á H.
