Effect of graphene substrate on the SERS Spectra of Aromatic bifunctional molecules on metal nanoparticles
López-Ramírez, María Rosa
; Castro, Jose Luis; Arenas Rosado, Juan Francisco; Soto-Martín, Juan; Otero, J.C. (2016-06-27)
The design of molecular sensors plays a very important role within nanotechnology and especially in the development of different devices for biomedical applications. Biosensors can be classified according to various ... -
Fundamentals and Applications of Surface-Enhanced Raman Spectroscopy (SERS)
López-Ramírez, María Rosa; Otero-Fernández-de-Molina, Juan Carlos; Soto-Martín, Juan; Castro, Jose Luis; Arenas Rosado, Juan Francisco (2019-05-16)
When a molecule is adsorbed on some metallic nanostructured surfaces such as silver, copper or gold, it can undergo an enormous enhancement of the Raman signal giving rise to the so called Surface-Enhanced Raman Scattering ... -
Mecanismos de Reacción Fotoquímicos de Nitro- y Nitrosocompuestos desde las Aproximaciones CASSCF y CASPT2: Relevancia de los procesos no adiabáticos
(Universidad de Málaga, Servicio de Publicaciones, 2007)Se ha abordado el estudio de los mecanismos de reacción fotoquímicos de nitrometano, nitrosometano, nitramida, nitrosamida y NNdimetilnitrosamina por métodos quimicocuánticos. Para ello se han estudiado las superficies ... -
Modeling the effect of the electrode potential in SERS by electronic structure calculations.
Ávila-Ferrer, Francisco José; Aranda Ruiz, Daniel; Roman-Perez, Jessica; López-Ramírez, María Rosa; López-Tocón, Isabel; Arenas Rosado, Juan Francisco; Otero-Fernández-de-Molina, Juan Carlos; Soto-Martín, Juan[et al.] (2018-07-18)
Surface Enhanced Raman Spectroscopy (SERS), due to the ability of greatly intensify the weak Raman signal of molecules adsorbed to metal surfaces, has proven to be a very useful tool to investigate changes in the electronic ... -
An MS-CASPT2 Study of the Photodecomposition of 4- Methoxyphenyl Azide. Role of Internal Conversion and Intersystem Crossing
Aranda Ruiz, Daniel; Ávila-Ferrer, Francisco José; López-Tocón, Isabel; Arenas Rosado, Juan Francisco; Otero-Fernández-de-Molina, Juan Carlos; Soto-Martín, Juan[et al.] (2019-02-13)
Aryl azides photochemistry is strongly dependent on the substituent relative position, as has been studied by time resolved resonant Raman (TR3) spectroscopy for 4-methoxyphenyl azide and its isomer 3-methoxyphenyl azide. ... -
Raman, SERS and DFT study of chemically-adsorbed thiobenzoic acid on silver nanoparticles
López-Ramírez, María Rosa; Arenas Rosado, Juan Francisco; Otero-Fernández-de-Molina, Juan Carlos; Castro, Jose Luis (2014-03-27)
Thiocarboxylic acids are organosulphur compounds with general formula RC(O)SH. They are related to carboxylic acids by the replacement of one oxygen by sulphur. Two tautomers are possible, written as RC(S)OH and RC(O)SH. ... -
Surface-Enhanced Raman spectroscopy of thiobenzoic acid on metal nanoparticles
López-Ramírez, María Rosa; Arenas Rosado, Juan Francisco; Otero-Fernández-de-Molina, Juan Carlos; Castro, Jose Luis (2014-07-31)
Molecules adsorbed on some metal surfaces such as silver, copper and gold, can exhibit enormous Surface-enhanced Raman Scattering (SERS). The SERS effect has historically been associated with substrate roughness on two ...
