Abstract
Within the framework of two parameter octahedral potential for a dipolar impurity in ionic crystals, it is possible for impurity to possess minimum-energy orientational configurations in two crystallographic directions simultaneously. Two combinations are ‹111›-‹110› and ‹111›-‹ 100›. Taking first model we have tried to explain paraelectric resonance in KI:OH- system with the effect of electric field. The data give good agreement for backward lines with the experimental data.
