Digital simulation model for bidimensional spectroelectrochemistry

A digital simulation model has been developed taking into account the simultaneous acquisition of one electrical and two spectroscopic signals generated in a bidimensional spectroelectrochemistry experiment. In this type of measurements, light absorption is simultaneously considered in both the normal and parallel directions to a plane electrode surface. The difficulty in resolving the equation giving the absorbance in parallel configuration as a function of the time and the distance to the electrode makes advisable the use of a digital simulation model. The model developed is valid for any potential controlled experiment, either in the equilibrium state or under finite/semi-infinite diffusion, that is to say, from thin-layer to bulk cells.
