The energy spectrum of the 7 F 3 multiplet of a Tb 3+ ion in one of the non‐equivalent positions (of D 2 symmetry) occupied by a rare‐earth ion in the Y 3 Al 5 O 12 crystallographic garnet structure is calculated. The energy spectrum of the 7 F 3 state is characterized by the presence of quasi‐doublet states formed by closely located Stark singlet states, that are effectively “mixed” in an external magnet field H . This inference is seriously confirmed by results of experimental studies of magnetopolarized luminescence on the radiative 5 D 4 → 7 F 3 4f–4f transition in Y 3 Al 5 O 12 :Tb 3+ . The optical transitions are identified, and the components of the g ‐factor of the 7 F 3 (Γ 2 , Γ 4 ) quasi‐doublets in the Y 3 Al 5 O 12 structure are determined.
