Simultaneous UV/vis Absorption in Parallel Configuration, Photoluminescence and Raman Spectroelectrochemistry

Analytical Chemistry is the science of chemical measurements that seeks to acquire the most comprehensive information about a chemical system. Recent advances in technology have facilitated the development of new combined analytical techniques capable of supplying analytical signals of different natures. These signals subsequently provide diverse information related to specific chemical reactions. This technical note proposes a new combination of three different spectroscopic techniques (UV/vis absorption spectroscopy in a parallel configuration, photoluminescence and Raman spectroscopy) with electrochemistry. To illustrate the capabilities of this new technique, two chemical systems (tris-(2,2' bipyridine)-ruthenium-(II) and ofloxacin) were selected. A comparison of the behavior of the two molecules during the electrode process demonstrates the advantages of obtaining several signals simultaneously in a single experiment.
