The vibration-dissociation kinetics of CO[SUB2]/N[SUB2] mixture is studied using three different models: 1) state-to-state approach, 2) quasi-stationary and 3)step-ladder approximations. Numerical simulations are aimed to describe the results of experimental findings in mixtures 2000ppm CO[SUB2] + N[SUB2] and 2000ppm CO[SUB2] + 10%N[SUB2] + Ar at T[SUBeq]=2326-2855 K and P[SUBeq]=0.75-2.59 bar. The yield of O-atoms from the dissociating CO[SUB2] is calculated in quasi-stationary and in step-ladder approximations and compared with the experimental one measured by ARAS technique during ∼100μs. The most interesting results are obtained at the early stage of vibrational intermode exchange in CO[SUB2] by means of state-to-state approach. The vibrational exchange of highly excited states (HES) of CO[SUB2] and N[SUB2] is studied on the base of step-ladder solution. [ABSTRACT FROM AUTHOR] |
