The electro-optic properties of 2-cyclooctylamino-5-nitropyridine and 2-(N-prolinol)-5-nitropyridine single crystals have been evaluated. The dependence of the electro-optic coefficients on the optical wavelength and the frequency of the applied electric field was determined. Enhancements of these coefficients near acoustic resonances were observed and are discussed in terms of elasto-optic contributions. We propose a simple expression for estimation of the limiting values of electro-optic and nonlinear-optical coefficients. In addition, the wavelength dependence of the electro-optic figure of merit for organic and inorganic materials is estimated.
