We can find BaTiO3 spectra in RRUFF and ROD databases (Lafuente et al., 2015, El Mendili et al., 2019). We will deconvolve the available spectra using q-BWF functions . The term "deconvolution" is largely used in Raman spectroscopy; its meaning is that of a decomposition in components of the spectrum. We proposed the q-BWF function as a generalization of the Breit-Wigner-Fano (BWF) line shape, to obtain an asymmetric form of the q-Gaussian function. The BWF line shape is a modified Lorentzian (Breit-Wigner) function, which is used to consider the asymmetry due to Fano resonance. The generalization we proposed in 2023 is using, in the BWF line, a q-Gaussian line shape instead of a Lorentzian profile. A q-Gaussian is a function based on the Tsallis q-form of the exponential function ; this generalized exponential is characterized by a q-parameter and when q is equal to 2, we have the Lorentzian function. If q is close to 1, we have a Gaussian function. For values of q between 1 and 2, we have a bell-shaped function with power-law wings ranging from Gaussian to Lorentzian tails. As shown on many occasions, the q-Gaussian is suitable for fitting Raman spectra, such as the q-BWF functions (see Sparavigna, 2024, and references therein).
