In the previous article, we discussed that the gas-phase interactions include electrostatic interactions. This tutorial describes the calculation of electrostatic interactions through electrostatic potential, commonly using ESPmax, ESPmin, and the positions of the electrostatic potential surface extrema to analyze reaction/binding sites/molecular polarity (Adv. Energy Mater. 2023, 13, 2300259). This article summarizes the steps for calculating … Read more
