Коливні спектри кристала (NH4)2BeF4 у параелектричній фазі
The vibrational spectra of the (NH4)2BeF4 crystal in the paraelectric phase (the space group symmetry No. 62) have been studied. In the framework of the group-theoretical analysis, the symmetry of vibrations in the crystal is classified. Using the first-principles approach and in the framework of th...
