The elastic-optical properties of liquids based on the grounds of acousto-optics are theoretically investigated. A relation for evaluation of the elastic-optical constant of liquids using only the index of refraction is obtained. The refractive index values maximizing the elastic-optic constant of polar and nonpolar liquids are determined. Calculations are performed for about 100 liquids and compared with known experimental data. This study significantly expands understanding of the acousto-optic effect and has practical use for predicting the elastic-optical constant of liquids and evaluation its wavelength dispersion.
