摘要
In this work we investigate the fast anomalous diffusion of hydrogen molecules in water using Car-Parrinello molecular dynamics simulations. We employ Voronoi polyhedra analysis to distinguish between void diffusion and void hopping. Our results indicate that a combination of both mechanism is sufficient to explain anomalous diffusion. Furthermore, we investigate the geometrical and electronical structure of the first solvation shell.
