Surface-Enhanced Raman Spectroscopy. It is a Raman spectroscopy based on the photons scattering by molecules adsorbed on rough metal surfaces or nanostructures. To answer the question about the use of q-Gaussians for SERS spectra, we start considering the spectrum of L-Cysteine as proposed by Sherman et al., 2020, in their "A surfaceenhanced Raman spectroscopy database of 63 metabolites". Then, we will consider the spectrum of Cysteamine and Homocysteine, as given by Sherman and coworkers too.
