Spectroelectrochemistry
Spectroelectrochemistry (SEC) is a set of multi-response analytical techniques in which complementary chemical information (electrochemical and spectroscopic) is obtained in a single experiment. Spectroelectrochemistry provides a whole vision of the phenomena that take place in the electrode process. The first spectroelectrochemical experiment was carried out by Theodore Kuwana, PhD, in 1964. The main objective of spectroelectrochemical experiments is to obtain simultaneous, time-resolved and in-situ electrochemical and spectroscopic information on reactions taking place on the electrode surface. The base of the technique consist in studying the interaction of a beam of electromagnetic radiation with the compounds involved in these reactions. The changes of the optical and electrical signal allow us to understand the evolution of the electrode process. The techniques on which the spectroelectrochemistry is based are: *Electrochemistry, which studies the interaction between elect ...

Theodore Kuwana
Theodore Kuwana (1931–2022) was a chemist and academic researcher known as the founding father of the field of spectroelectrochemistry. Kuwana's academic career included appointments at California Institute of Technology, the University of California, Riverside, Case Western Reserve University, Case Institute of Technology, Ohio State University, and finally at the University of Kansas. At KU, he was Regents Distinguished Professor of Chemistry and Pharmaceutical Chemistry, the Director of the Center for Bioanalytical Research, and Emeritus Distinguished Professor. He served as managing director of the Analytical Sciences Digital Library. During his career, Kuwana mentored more than 70 graduate students. Early life and education Theodore Kuwana, a son of Japanese immigrant (''Issei'') parents Yoshino and Nenokichi Kuwana, was born August 3, 1931, in Idaho Falls, Idaho, in the United States. Kuwana wrote, "I was the youngest of six children; my parents were immigrant ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
UV-Vis Absorption Spectroelectrochemistry
Ultraviolet-visible (UV-Vis) absorption spectroelectrochemistry (SEC) is a multiresponse technique that analyzes the evolution of the Absorption spectroscopy, absorption spectra in UV-Vis regions during an electrode process. This technique provides information from an Electrochemistry, electrochemical and Spectroscopy, spectroscopic point of view. In this way, it enables a better perception about the chemical system of interest. On one hand, molecular information related to the electronic levels of the molecules is obtained from the evolution of the spectra. On the other hand, kinetic and thermodynamic information of the processes is obtained from the electrochemical signal. UV-Vis absorption Spectroelectrochemistry, SEC allows qualitative analysis, through the characterization of the different present compounds, and quantitative analysis, by determining the concentration of the analytes of interest. Furthermore, it helps to determine different electrochemical parameters such as abso ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
