Abstract

We performed Raman scattering measurements of lattice modes and powder neutron diffraction measurements to test the symmetry changes in pyridinium tetrafluoroborate (PyBF₄) caused by the phase transitions at temperatures 240 and 205 K. From the powder diffraction data obtained we found out the sequence of phase transitions in PyBF₄: R3̄m ^{240 K}→ C2 ^{240 K}→ P2. The number of lattice modes found in the Raman scattering experiment is in agreement with the lowering of symmetry.
