We report on the first investigation of the effect of nonlinear optical activity (NOA) in crystals (dependence of the angle of rotation of the polarization plane on light intensity) which is dependent on the electronic nonlinearity. Measurements are made in LiI03 crystals. Electronic NOA is separated from the thermal effect background and is (1 +0.6) X 10 "11 deg-cm-w " ë
