Abstract

Tsallis q-Gaussian functions are probability distributions possessing a shape which can be stretched from a Lorentzian to a Gaussian profile, according to the q-index parameter of their generalized exponentials. As we have previously shown, the q-Gaussian functions can be successfully applied to the deconvolution of Raman bands. Here we consider them for being used in the analyses of the Surface Enhanced Raman Scattering (SERS) spectral bands. The case studies here considered are the SERS spectra published by Sherman et al., in 2020, of L-Cysteine, Cysteamine and Homocysteine. Sherman and coworkers prepared these metabolites in silver colloids with sodium citrate.
