Vibrational spectra of β-LiNH4SO4 crystals in the ferroelectric phase (space group No. 33) are studied. The vibrational symmetry is classified using group-theoretical analysis. Vibrational frequencies of crystal structural elements are calculated ab

The effect of uniaxial stresses applied along the principal crystallographic directions on the dispersion and temperature dependences of birefringence of K2SO4 crystals is studied. The birefringence is found to be sensitive to uniaxial stresses. The

The spectral and baric dependences of the birefringence of α-LiNH4SO4 crystals are studied. It is found that the birefringence is rather sensitive to uniaxial compressions. A baric shift of the isotropic point to longer or shorter wavelengths depend
