| 摘 要： | We deduce new expressions for g-factors of the 3d9 ions with a compressional tetragonal symmetry, in which we consider not only the contribution from the spin-orbit coupling of the central transition metal ion but also that of the ligand orbits as well as the admixture of 2B1g into 2A1g (ground state). By using the new formulae, the electron paramagnetic resonance g-factors for NaCl:Ni+(I) are studied. Thus, the puzzle that the g‖-shift is positive is reasonably explained.
