The versatility of spectroelectrochemistry is increasing due to the possibility of using several electrochemical techniques in different spectral regions depending on the purpose of the study and the information of interest.
The main advantages of spectroelectrochemical techniques are:
*The simultaneous information is obtained by different techniques in a single experiment, increasing the selectivity and the sensitivity.
*Both qualitative and quantitative information can be obtained.
*The possibility of working with a small amount of sample, saving it for future analysis.
Due to the high versatility of the technique, the field of applications is considerably wide.
*Study of reaction mechanisms, where the oxidation and reduction of the species involved in the reaction can be observed, as well as the generation of reaction intermediates.
*Characterization of organic and inorganic materials, that allow to understand the structure and properties of the material when is perturbed by a signal (electric, light, etc.).
*Development of spectroelectrochemical sensors, which are based on optical and electrical responses, capable of providing two independent signals about the same sample and offering a self-validated determination.
*Study of catalysts, obtaining relationships between the electrochemical and spectroscopic properties and their photochemical and photophysical behaviour.
*Study different processes and molecules in biotechnology, biochemistry or medicine. 
*Determine specific properties and characteristics of new materials in fields such as energy or nanotechnology.
