In this paper, the low lying levels of d1 and low-spin d5 metal complexes possessing ground 2T2 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.
