Charge Transfer mechanism in the Surface Enhanced Raman Scattering of 2,2'-bipyridine recorded on a silver electrode
(2018-07-17)Nowadays, Surface Enhanced Raman Spectroscopy (SERS) has become a powerful technique to investigate the electronic structure of surface-molecule hybrid systems due to the huge enhancement of the Raman signal. It is established ... -
Comparative study of different theoretical approaches for modeling the dependence of the SERS vibrational wavenumbers on the electrode potential
(2019-07-25)Surface-enhanced Raman scattering (SERS) is a powerful technique to study the electronic structure of charged metal-molecule interfaces, which are relevant in many fields like electrochemistry, heterogeneous catalysis or ... -
Effect of different excitation wavelength on SERS spectra of pyridine
(2018-05-14)SERS spectra of pyridine has been already recorded on a silver electrode in a potential range from 0.0 to -1.40 V with a saline solution, pyridine / KCl (0.1M / 0.1M), by using the 514.5 nm exciting line. Under these ... -
Frequency shift on the potential-dependent surface-enhanced Raman scattering of pyridine: simplified models for metal and solvent effects
(2018-07-18)The electronic structure of adsorbates is altered when it interacts with a surface, modifying the properties of both entities and giving rise to interesting phenomena related to heterogeneous catalysis or molecular ... -
Modeling the effect of the electrode potential in SERS by electronic structure calculations.
(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 ...
