Spectroelectrochemistry (SEC)

Definition - What does Spectroelectrochemistry (SEC) mean?

Spectroelectrochemistry (SEC) refers to a field of chemistry that combines the examination of electrochemical responses of a specimen with spectroscopy to provide a more thorough analysis of any redox reactions and electron transfer dynamics that may be present. Corrosion is an example of a redox reaction that may occur in a given specimen.

Corrosionpedia explains Spectroelectrochemistry (SEC)

Spectroelectrochemistry (SEC) collectively entails various techniques to collect spectroscopic and electrochemical information about a metal's surface or its environment. This is particularly useful when examining electrochemical reactions such as those in an electrochemical cell, which is a device or a mechanism that generates electrical energy from a chemical reaction or uses electrical energy to initiate a chemical reaction. Corrosion is an example of an electrochemical process.

Working electrodes must be part of the system for a reaction to occur. Electronic (UV-visible) transmission and reflectance SEC is an effective approach for studying electrodes and the mechanisms they facilitate. Most redox reactions and homogeneous reactions that are initiated electrochemically within the boundaries of a diffusion layer can be examined using SEC.
