    • SERS spectrum of gallic acid obtained from a modified silver colloid 
      Garrido, C.; Díaz Fleming, Guillermo; Campos Vallette, Marcelo (Elsevier, 2016)
      Two different crystals of the gallic acid were microscopically separated from a p.a. commercial product. The Raman spectra analysis allowed distinguishing monomeric and dimeric structures. The vibrational wave numbers were ...
    • Surface-enhanced Raman scattering study of L-tryptophan 
      Aliaga, A. E.; Osorio Román, Igor; Leyton, P.; Garrido, C.; Cárcamo, J.; Caniulef, C.; Célis, F.; Díaz Fleming, Guillermo; Clavijo Campos, Ernesto; Gómez Jeria, Juan; Campos Vallette, Marcelo (2009)
      Surface-enhanced Raman scattering (SERS) spectra of tryptophan (Trp) were obtained. A unique SERS spectrum of Trp, corresponding to the most stable conformation and orientation on the metal surface, is observed after a ...
