Off-center displacement of Nb in KNbO3 is explained in terms of the pseudo Jahn–Teller effect in octahedral clusters [NbO6]. Strength of this symmetry-breaking effect is determined by electron-vibrational coupling and by the HOMO–LUMO energy gap. Under applied ambient pressure, the energy gap increases weakening the pseudo Jahn–Teller instability, reducing off-center displacement of Nb in trigonal...
