| Abstract | dc.description.abstract | Arginine amino acid (Arg) has been vibrationally studied through its infrared, Raman and surfaceenhanced
Raman scattering (SERS) spectra, and theoretical calculations. Net charge is used to predict
the possibility to obtain the SERS spectrum of Arg in colloidal solution. The interpretation of the SERS
spectral data suggests that the Arg–Ag nanoparticles interaction in a colloidal solution and in the case of
the Arg coated by Ag is mainly verified through the guanidinium moiety. Theoretical calculations performed
by using extended Hückel theory method for a model of Arg interacting with an Ag cluster support
the observed SERS experimental result. | es_CL |
