A generalized lateral interactions function to fit voltammetric peaks of self-assembled monolayers

•A function derived from a theoretical model fits adsorption voltammetric peak.•This approach is dedicated to SAMs where interactions between electroactive centers are possible.•The fitting procedure is easy to implement and gives access to characteristic parameters of a voltammetric peak (i.e. Ep, ip, FWHM, Γ, and interaction parameter).

From the generalized lateral interactions model and via a few mathematical approximations, a suitable regression function has been developed in order to fit voltammetric peak of redox responsive SAM for extracting the characteristic parameters. The efficiency of the generalized lateral interactions function was tested on simulated and raw data.
