✦ Synopsis

Recent experimental tnvesttgatrons of the popufar~on evofutron of the vibrational states of CO dduted in Ar indtcatc

Ihat the rates of tbc reactions CO( 1) + CO(u) -CO(O) + CO(u + 1) * ti Increase with u for u = l-3, and that they are approxrmatcly constant for u = 3-5. This surpnsmg and unexplained behavlour can be understood from a nonstatistvxl dlstnbutlon of the localrsed higher viiratlonal excitations u 2 2 such that processes with u 2 3 xe accelerated by approhimatcly one order of rn~~n~tude over those with v = 1. Therefore the reactron with u = I acts as a bottleneck VI the upward cascade.
