We argue that the 3 A 2 state considered by Oleś in phys. stat. sol. (b) 236 , 281 (2003) for the d 2 system occurring in the V 3+ ion in V 2 O 3 and LaVO 3 as well as in the Ti 2+ ion in TiO and in many other oxides is wrong. The proper ground state is 3 T 1 g – its 9‐fold degeneracy is further split in a crystal by intra‐atomic spin–orbit interactions and lattice distortions. (© 2005 WILEY‐VCH Verlag GmbH & Co.
