We propose a versatile function to fit adsorption voltammetric peak in order to extract the characteristic parameters such as the fullwidth at halfmaximum, the peak potential, the peak current and the surface coverage. Based on the generalized Gaussian function and supported by generalized lateral interaction model, this method has been tested on different electroactive self-assembled monolayers (i.e. ferrocene, bithiophene, tetrathiafulvalene and radical aminoxyl units).
