  We show that the interplay between spin-orbit coupling and cubic symmetry
breaking in SrTiO3 results in a highly anomalous Zeeman effect of conduction
electrons substantially different among the three conduction sub-bands and
strongly dependent on their splitting. This effect can be measured via
electrically-driven spin resonance enabled by the interplay between electron
hopping and spin-orbit coupling, and enhanced by the near-degeneracy of the
conduction sub-bands. The proposed effects can provide a unique insight into
the electronic properties of SrTiO3 and its heterostructures.
