• Procesos de Resonancia Raman en Espectroscopía SERS 

      Román Pérez, Jessica (UMA Editorial, 2015)
      Se han estudiado diversas cuestiones fundamentales relacionadas con el origen de la enorme intensificación que experimenta el espectro Raman de una molécula situada en las proximidades de ciertas superficies metálicas. La ...
    • Selection rules of surface-enhanced Raman scattering: the role of the out-of-plane vibrations 

      Aranda, Daniel; Valdivia, Samuel; Avila, Francisco J.; Soto-Martin, Juan; López-Tocón, Isabel; [et al.] (2019-07-25)
      The electromagnetic/plasmonic (SERS-PL) and the chemical (usually involving resonant photoinduced metal-adsorbate (M-A) charge transfer processes (SERS-CT:M-A+hn-->M+-A-)) mechanisms are recognized as the two main contributions ...
    • SERS study of different species of p-aminothiophenol adsorbed on silver nanoparticles 

      López-Ramírez, María Rosa; Ávila Ferrer, Francisco José; Otero-Fernandezde-Molina, Juan Carlos; Soto-Martin, Juan (2018-06-01)
      In the present work we have focused the discussion on the experimental and theoretical SERS spectra of the organic compound pATP recorded on silver colloids. The huge SERS of pATP on metal substrates is significantly ...
    • Sobre la fenología reproductora de las algas rojas en el litoral de sudeste de España (Alborán Oriental) 

      Soto-Martin, Juan; Conde Poyales, Francisco (Universidad de Málaga, Servicio de Publicaciones, 1989)
      Se describe la fenología reproductora observada en 86 táxones de algas rojas del Sureste de España. Paralelamente, y en base al análisis efectuado durante seis anos (19831988) de 2.543 poblaciones pertenecientes a 23 ...
    • Sobre la presencia de algunas especies de algas tropicales en el litoral del sureste ibérico 

      Soto-Martin, Juan; Conde Poyales, Francisco (Universidad de Málaga, Servicio de Publicaciones, 1987)
      We make the commentary of four tropical species found at different states in SE of Spain, scarcely quoted in the Mediterranean Sea. This species are: Dipterosiphonia dendritica (Ag.) Schmitz in Engl. et Prantl, Liagora ...
    • Surface-enhanced photoinduced charge transfer processes in metal-molecule nanoclusters 

      Centeno, Silvia; Ruano, Cristina; Román-Pérez, Jéssica; López-Tocón, Isabel; Soto-Martin, Juan; [et al.] (2013-10-29)
      This work deals with the unexplained efficiency of the electrode potential (EV) in tuning the energy of Charge Transfer (ECT) electronic states of hybrid systems formed by molecules and metal nanostructures. Huge energy ...
    • The role of the electrolyte on the SERS spectra of pyridine 

      López-Tocón, Isabel; Soto-Martin, Juan; Otero-Fernandezde-Molina, Juan Carlos (2016-04-22)
      SERS spectra of pyridine has been recorded on a silver electrode in a potential range from 0.0 to -1.20 V with a saline solution, pyridine / KCl (0.1M / 0.1M), by using the 514.5 nm exciting line by us [1]. Under these ...
    • Using SERS to probe electric capacitive enhancement in nanometer-size hot spots 

      Centeno, Silvia; Ruano, Cristina; Roman-Perez, Jessica; López-Ramírez, Jessica; Soto-Martin, Juan; [et al.] (2014-09-10)
      Although the electromagnetic mechanism related to localized plasmons of the metal is the most important contribution in SERS, the chemical interaction between metal and molecule plays a crucial role. In SERS electrochemical ...
    • Using Surface-enhanced Raman scattering to probe the capacitance of metallic nanostructures 

      Centeno, Silvia; Ruano, Cristina; Román-Pérez, Jéssica; López-Tocón, Isabel; Otero-Fernandezde-Molina, Juan Carlos; [et al.] (2013)
      Though it is generally accepted that the electromagnetic mechanism related to the excitation of localized plasmons of the metal surface is the most important contribution in SERS, the chemical interaction between molecule ...
