A strong decrease in the g-factor anisotropy was revealed by optically detected magnetic resonance for self-napped Jahn-Teller holes both isolated and forming self-trapped excitons in AgCl nanocrystals embedded into the KCl crystal lattice. This implies a considerable suppression of the Jahn-Teller J-T effect in nanoparticles. A rather general mechanism of the suppression of the Jahn-Teller effect in nanocrystals is developed taking into account the additional deformation field appearing because of the strong vibronic interaction at the interface.
