Temperature-Phase Dependence of the Vibration Spectrum and Orientation Mobility of the Tetrafluoroborate Ion in n-Bu4NBF4 Organic Salt

详细

The structural and dynamic properties of a tetrafluoroborate ion in n-Bu₄NBF₄ organic salt at different temperatures and phase states were studied by oscillation spectroscopy methods. The results of calculations of the energy and relaxation parameters have shown that in the plastic phase, a \({\text{BF}}_{4}^{ - }\) ion is characterized by a low reorientation energy as compared with that of the crystalline phase.
