In situ Raman spectroelectrochemistry of azobenzene monolayers on glassy carbon.
In situ Raman spectra of chemisorbed azobenzene (AB) monolayers on glassy carbon (GC) electrodes were observed under potentiostatic conditions in acetonitrile (ACN) with tetrabutyl-ammonium tetrafluoroborate (TBA-BF4). The Raman intensities of these spectra were high below -1000 mV, and this is attributed to the change in absorbance of AB on GC. In this paper, we describe chemisorbed AB molecul...
متن کاملSimultaneous Ground-Based Remote Sensing of Water Vapor by Differential Absorption and Raman Lidars
Water vapor is well known to be a critical component in many aspects of atmospheric research, such as radiative transfer and cloud and aerosol processes. The distribution of water vapor in the atmosphere is highly variable, both in time and in space, and has proven to be very difficult to measure accurately. The U.S. Department of Energy’s Atmospheric Radiation Measurement (ARM) Program’s overa...
متن کاملIn situ raman spectroelectrochemistry of electron transfer between glassy carbon and a chemisorbed nitroazobenzene monolayer.
In situ Raman spectroscopy was used to monitor 4-nitroazobenzene (NAB) in an electrochemical cell, both as a free molecule and as a chemisorbed monolayer on a glassy carbon (GC) electrode surface. Reduction of free NAB exhibited two well-defined voltammetric couples in acetonitrile, and the accompanying spectral changes supported a mechanism involving two successive 1-e(-) transfers. Raman spec...
متن کاملRaman Spectroelectrochemistry of Polyaniline Synthesized Using Different Electrolytic Regimes – Multivariate Analysis
Potentiostatic, galvanostatic and cyclic potentiodynamic depositions of polyaniline were studied by cyclic voltammetry and in-situ Raman spectroscopy. Multivariate analysis of the spectroelectrochemical data including evolving factor analysis, multivariate curve resolution and 2Dcorrelation spectroscopy was applied to resolve overlapped bands in Raman spectra and to assign them reliably. Oxidiz...
متن کاملSpatially resolved Raman spectroelectrochemistry of solid-state polythiophene/viologen memory devices.
A three terminal molecular memory device was monitored with in situ Raman spectroscopy during bias-induced switching between two metastable states having different conductivity. The device structure is similar to that of a polythiophene field effect transistor, but ethylviologen perchlorate was added to provide a redox counter-reaction to accompany polythiophene redox reactions. The conductivit...
