Valence electrons excitations of (NH4)2SO4 crystals have been studied by the spectral ellipsometry method using synchrotron radiation in the photon energy range E < 9.5 eV. Large anomalies of the temperature dependences of dielectric permittivity and intensity of reflected radiation have been found in the temperature range close to the phase transition point between para- and ferroelectric phases.
