ABSTRACT: We report a technique for conducting semiinfinite diffusion spectroelectrochemistry on an aqueous microdrop as an easy and economic way of investigating spectroelectrochemical behavior of redox active compounds and correlating spectroscopic properties with thermodynamic potentials on a small scale. The chemical systems used to demonstrate the aqueous micro-drop technique were an absorbance based ionic probe [Fe(CN)6]3-/4- and an emission based ionic probe [Re(dmpe)3]2+/+. These chemical systems in a micro-drop were evaluated using cyclic voltammetry and UV--visible absorbance and luminescence spectroscopies.
