title: Semi-infinite linear diffusion spectroelectrochemistry on an aqueous micro-drop.
abstract: We report a technique for conducting semi-infinite diffusion spectroelectrochemistry on an aqueous micro-drop 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.
