Electrochemical and surface enhanced Raman scattering spectrochemical study of phytic acid on the silver electrode

Article Abstract:

Electrochemical and surface enhanced Raman scattering (SERS) spectroelectrochemical measurements were used to report the studies of the structure and anticorrosion features of two kinds of self-assembled monolayers (SAMs) of IP6 at the silver surface under various pH values, 1.27 and 13. Based on in situ SERS electrochemical measurements, a tentative explanation for the difference in corrosion potentials of two kinds of the silver surfaces in the presence of SAMs formed from completely protonated or deprotonated IP6 molecules are presented.

Time-domain Raman measurement of molecular submonolayers by time-resolved reflection spectroscopy

Article Abstract:

The first observation of vibrational coherences of cresyl violet adsorbed at submonolayer coverage on a fused silica by time-resolved reflection measurements is discussed. A vibrational spectrum of the dye at submonolayer coverage, which corresponded to its resonance Raman spectrum, was obtained in the range 0-800 cm(super -1) by a Fourier transform analysis of the reflection signal.

Determination of anisotropic optical constants and surface coverage of molecular films using polarized visible ATR spectroscopy. Application cytochrome c films

Article Abstract:

The study describes a method to determine the anisotropic optical and surface coverage of molecular films using polarized attempted total reflectance (ATR) absorbance measurements. Anisotropic values of the imaginary part of the refractive index (k) allow for the determination of the surface coverage and one order parameter of the film.
