In the previous figures, we proposed the q-Gaussian deconvolutions of some SERS bands, the data of which have been provided by Sherman et al., 2020. The centres of the q-Gaussian components (in cm -1 ) are as follows: 613, 633, 719, 803. The reason of the shift is related to "a withdrawal of electron density from the C-S bond because of bonding of the sulphur to the silver", and, as stressed by Michota and coworkers, "the position of these bands is sensitive to the surrounding electrolyte". The bands in the range 930 -1020 cm -1 are ascribed to skeletal vibrations, "mainly C-C stretching coupled with the C-N stretching". Further SERS experimental data had been provided by the same researchers, A. Michota, A. Kudelski and J. Bukowska, in 2000. In their article of 2002, Figure , we can see the SERS spectra (range 400-12 00 cm -1 ) of Cysteamine on roughened silver and gold, with the evident presence of G and T bands. "The monolayers formed on silver contain significantly higher portion of a trans conformer than monolayers on gold. Probably monolayers on silver are self-assembled in such a way that higher portion of the amino groups is unbonded to the surface, thus being available for attaching other molecules" .
