Abstract:	A molecular dynamics simulation study of methanesulfonic acid has been carried out using a reliable force field in a large range of temperatures. Several thermodynamic, structural, and dynamical properties have been calculated and compared with the available experimental data. The density, the shear viscosity, the heat of vaporization, and the melting temperature results, calculated from this force field, are in a good agreement with the experimental data. Analysis of the influence of the hydrogen bonds in structural and dynamical properties has also been performed. The continuous and interrupted methodologies to compute hydrogen bonding lifetimes have been applied. The interrupted hydrogen bond lifetimes values are consistent with the diffusion and viscosity coefficients. The activation energies of the self-diffusion, the reorientational motions, and the hydrogen bonding lifetimes are coincident.
