Semi-empirical molecular dynamics is used to simulate several gaseous atomic\nhydrogen interactions with hydrocarbon grains in space: recoil, adsorption,\ndiffusion, chemisorption and recombination into molecular hydrogen. Their\nprobabilities are determined by multiple numerical experiments, as a function\...

Fig. 9a) regardless of the type of functional group. The exponential curves and plateau describe the gradual resistance of the molecules to evaporate as the molecular mass increases. The trend is consistent with the increase ofactivation energyrequired to bring the molecules into thegaseous state...
