Abstract
collisions through a mixed quantum-classical method, based on the quantum treatment of molecular vibrations, for vibrationally excited states up to v = 40. Such a large V-T/R coefficient database is quite unprecedented, and the comparison of the efficiency of the related processes with the corresponding V-V coefficients shows that vibrational relaxation plays a very relevant role in high temperature regimes.
