Figure 12. Distribution of the angle between the molecular axis and the surface normal (θ) at the
time of the reaction (see text for definition) for both the direct and the indirect mechanisms (red
and blue lines, respectively). To increase the resolution of the data, for each molecule have been
reported the two values of θ obtained inverting the N atoms (i.e., the angles θ and 180◦ − θ have
been reported for each atom). The incidence energy Ei is reported as inset.

*.dat files contain the theta (degrees) of the reacted trajectories at the moment of the dissociation.
