Taking the plane of the electrode surface as a spatial reference, normal-beam and parallel-beam UV−vis absorbance signals are jointly analyzed, revealing important experimental differences between the two kinds of signals. Two different chemical systems are selected to show the possibilities of the bidimensional spectroelectrochemistry:  a simple diffusive process and an adsorptive electrode reaction. Comparative results show clearly that the two kinds of spectroscopic signals, both normal and parallel to the electrode surface, have to be used together in the study of any electrode reaction scheme. 0003-2700 https://hdl.handle.net/10259/11116 10.1021/ac0014459 1520-6882 Spectroelectrochemistry Diffusion layer Adsorption Electropolymerization Optically transparent electrodes Long-pathway thin layer cells Bidimensional Spectroelectrochemistry
