Temperature Dependence of the Rate Constants of the VV Energy Exchange for N2(v = 1) + O2(v = 0) → N2(v = 0) + (v = 1)
Jongbaik Ree*, Keun Ho Chung, Hae Jin Kim
The vibration-vibration energy exchante of N2(v = 1) + O2(v = 0) → N2(v = 0) + O2(v = 1) has been investigated, in particular, at low temperatures. The energy exchange rate constants are calculated by use of the solution of the time-dependent Schrodinger equation with the interaction potential of the colliding molecule as a perturbation term. The predicted rate constants are significantly agree with a experimental values in the range of 295∼90。K. The consideration of the VV-VT coupling decreases the predicted pure VV energy exchange value by a factor of ∼2. When the collision frequency correction is introduced, the VV-VT rate constant is consistent with the observed value in the liquid phase. The consideration of the population of the rotational energy level increases the VV-VT value significantly.
