There are different spectroelectrochemical techniques based on the combination of spectroscopic and electrochemical techniques. Regarding electrochemistry, the most common techniques used are:
*Chronoamperometry, which measures current intensity as a function of time by applying a constant difference of potential to the working electrode.
*Chronopotentiometry, which measures the difference of potential as a function of time by applying a constant current.
*Voltammetry, which measures the change of current as a function of the linear change of the working electrode potential.
*Pulse techniques, which measure the change of current as a function of difference of potential, applying pulse potential functions to the working electrode.
The general classification of the spectroelectrochemical techniques is based on the spectroscopic technique chosen.
