Next, we analyse other HCN(v1, v2, v3) populations and compare them with experiment. i) In the present work, we found that the population of the HCN(0,0,0) vibrational ground state is < 1%, reproducing Bethardy et al.'s results for the title reaction, within the theoretical/experimental uncertainties. ii) In addition to the bending excitation, ~80% in the present study, we found hot C-H stretch and cold C-N stretch distributions. Figure presents the distributions of energy deposited in each HCN product degree of freedom, where it can be seen that while the CN stretch mode appears excited by 40%, the CH stretch mode appears excited by 80%. These theoretical results simulate the experimental evidence and other theoretical results for the propane reaction. Therefore, given that the reactant CN is in its vibrational ground-state, the CN stretching mode does not behave like a spectator mode, and the excitation of the CH stretching mode can be explained because the motion related to the transfer of the hydrogen atom to the attacking CN radical is very similar to the v3 normal mode motion in the HCN product (see bottom of Figure ). iii) Experimentally a significant inversion population between HCN(002)-(001) and HCN(001)-(000) was reported. In the present work, the QCT/PES-2023 results reproduce this behaviour: 6.24, 4.19, 0.66% for the HCN(002), (001) and (000), respectively. Finally, iv) the strong inversion of population between HCN(101)-(100) experimentally reported was simulated in our calculations, 7.96 and 0.33 %, respectively. In sum, the agreement with the experimental evidence in fine measurements as state-to-state results lends confidence to the theoretical tools used, PES-2023, QCT calculations and NMA analysis.
