Kinetics of 1H→13C NMR cross-polarization in polymorphs and solvates of the antipsychotic drug olanzapine

► Solid-state 1H→13C NMR cross-polarization in polymorphs and solvates of olanzapine. ► Non-classical I-I*-S CP model. ► Principal component analysis (PCA) of the CP kinetics parameters. ► The study established ranges of the CP kinetics parameters for various functional groups.
