(a) The example of a fit of Raman spectrum using the equation (2). (b) Temperature dependence of the integrated reduced intensity and FWHM of the CP of the KLTN/0.05/0.27 single crystal at the VV scattering. The dotted and dash-dotted lines in (b) are guide to eyes. (c) The frequency shift of the first order TO1 and TO2 modes (upper half) and the variation of the intensity of the 2TA mode (lower half) at the VV scattering of the KLTN/0.05/0.27 crystal as a function of temperature.
