Short summary
In the gaseous reaction, the activation energy for the hydrolysis of HNSO2 catalyzed by MSA was only 0.8 kcal mol−1. Atmospheric Cluster Dynamic Code kinetic simulations disclosed that sulfamic acid markedly enhances the assembly of a methanesulfonic acid–methylamine-based cluster. At the air–water interface, the NH2SO3 and H3O+ ion formation mechanism and the proton exchange mechanism were observed.
