Temperature dependences of the optical path difference by the variable part of refractive index D = (n − 1)l and the components ε′ and ε′′ of complex dielectric permittivity for NH₄HSeO₄ single crystal are studied in the temperature range of 220–300 K. Anomalous behaviour of these dependences in t...
