The Voigt functions, convolutions of Gaussian and Lorentzian functions, and the q-Gaussian functions can be used as line shapes in Raman spectroscopy for the analysis of spectra . The Voigtian convolution possesses a bell shape with a Gaussian kernel and wings (tails) which are of the Lorentzian form. According to , the asymptotic solution of Voigtian expansion has the leading term equal to 𝑎 0 ⁄ 𝜋𝑥 2 , where x is the variable. The Voigt functions, or their approximations as pseudo-Voigtian functions, which are linear combinations of Gaussian and Lorentzian functions, are suggested for instance in , because of their corresponding time correlation functions related to the fundamental mechanisms of Raman photonic emissions. Let us also note that the Voigt profiles are intermediate between the Lorentzian and Gaussian outlines. The reason of using the Voigt functions is therefore also motivated by the fact that "intermediate" profiles are usually displayed by the Raman spectral lines .
