The effect of uniaxial pressure (σm ≤ 200 bar) on the spectral (300-800 nm) and temperature (77-300 K) dependences of the refractive indices of Rb2ZnCl4 crystals are investigated. The baric dependences of the electron polarizability, specific refraction and the parameters involved in the Sellmeier formula are calculated.
