Spectroelectrochemistry

Spectroelectrochemistry Is A Field Of Study That Combines The Principles Of Spectroscopy And Electrochemistry To Study The Effects Of An Electrical Potential On A Given Chemical Reaction Or Reaction Mixture. It Is Used To Investigate The Kinetics And Thermodynamics Of Both Oxidative And Reductive Species In Aqueous Or Non-Aqueous Electrolytic Solutions. The Study Of Spectroelectrochemistry Is Concerned With The Effects Of Light On Chemical Systems. This Type Of Study Involves The Application Of Electrical Current Or Voltage To A Sample That Has Been Exposed To Light Of A Certain Wavelength. By Setting Different Levels Of Voltage, Various Levels Of Chemical Reaction Can Be Investigated Because Of The Difference In The Rate Of Color-Forming Reactions That Occur In Each State. As The Electrical Potentials Increase, Oxidation Or Reduction Of Electrons Can Take Place. In Many Cases, The Components Of A Reaction Or Sample Can Be Determined Using Spectrophotometry. This Involves Measuring The Intensity Of Emitted Light Over Various Wavelengths. Variations In Absorbance Or Transmission Spectra Can Then Be Used In Conjunction With An Electrochemical Cell To Determine The Concentration Of A Substance Within A Given Mixture. This Is Useful For Tracing The Path Of A Particular Reaction And Analyzing Its Rate Of Production.
