DESCRIPTION:Dr. Michal Zalibera\, Institute of Physical Chemistry and Chem
 ical Physics\, Faculty of Chemical and Food Technology\,  Slovak Universi
 ty of Technology\, Bratislava\, Slovakia\nElectrochemical processes repres
 ent a major class of chemical reactions in the laboratory as well as in in
 dustrial applications. Analytical electrochemistry continues to be an exce
 llent method to yield energy data in the form of redox potentials\, to det
 ermine concentrations\, and to elucidate formal reaction mechanisms throug
 h kinetic analysis. However\, alone\, is not able to characterize unknown 
 species that are formed as intermediates or as products in a redox reactio
 n. The combination of electrochemistry with species-focused spectroscopy\,
  commonly known as spectroelectrochemistry (SEC)\, can solve this proble
 m and thus allow for a more complete analysis of electron-transfer process
 es and complex redox reactions. This semi-tutorial presentation will provi
 de the audience with an insight into a variety of SEC techniques including
  UV-Vis-NIR\, IR\, EPR and NMR-spectroelectrochemistry. The advantages\, d
 rawbacks and potential limitations of each method\, particularly with resp
 ect to in-situ or online applications\, will be discussed. Examples fr
 om the STU lab will be used to illustrate the power of the combination too
 ls from the SEC toolbox in the understanding of the redox chemistry of ful
 lerenes\, organic push-pull super-acceptors\, non-innocent ligand organome
 tallic complexes as well as supramolecular devices.  Finally\, as a small
  detour\, few advanced pulsed EPR and ENDOR methods extending the SEC anal
 ysis will be introduced.
