Finally, other dynamic properties, such as product rotational (PRD), product translational (PTD) and product angular (PAD) distributions, were analysed. Figure (bottom, right panel) shows the HCN rotational distribution at 298 K. The HCN product presents a cold and broad rotational distribution, which is associated with a linear and soft transition state, generating little torque as the reaction evolves. In the same Figure and panel, PTD is shown at 298 K. Like in the case of PRD, a thermal distribution is found, and both distributions reproduce the experimental evidence. Interestingly, similar thermal distributions were reported theoretically by Glowacki et al. for the reaction with propane, and experimentally by Huang et al. for the reactions with n-butane, n-pentane and n-hexane, although it is important to note that different initial conditions were used in these studies. However, in spite of the different conditions in each case, these results seem to suggest a general tendency for the CN + alkane reactions. Finally, the PAD (HCN product with respect to the reactant CN radical) represents another interesting dynamics property. It is given by the differential cross section (DCS), i.e., the variation of the reaction cross section, r with respect to the solid angle (),
