SUPPLEMENTAL MATERIAL for High-Temperature Non-Equilibrium Atom-Diatom Collisional Energy Transfer

The supplementary material gives a brief introduction of quasi-classical trajectory (QCT) simulation; the systems studied in current work and their potential energy surfaces; the state-to-state transition rate coefficients calculation method; details of the proposed semi-analytical ``Activation-Saturation'' (AS) model; examples of the vibrational energy relaxation of N+N2 after passing strong shocks in hypersonic flows.
