Abstract

Abstract In this paper, the low lying levels of d 1 and low-spin d 5 metal complexes possessing ground 2T 2 term are considered. Strong spin–orbital interactions is taken into account along with the axial (trigonal or tetragonal) component of the crystal field. In the framework of the semi-classic adiabatic approximation, vibronic Jahn–Teller and pseudo Jahn–Teller interactions acting within the ground manifold are also considered. The influence of the low-symmetry crystal fields, covalence reduction factor, spin–orbital and Jahn–Teller interactions on the anisotropy of g-factors, temperature independent paramagnetic contributions, and magnetic susceptibility is elucidated.
