Abstract
A kinetic model, taking into account the rovibrational state-to-state energy transfers within the
first vibrational dyad of ozone, has been applied to describe the (100)
(001)
Coriolis-assisted intermode transfer occurring upon O
3 - N
2 and O
3 - O
3
collisions. The state-to-state rate coefficients have been calculated by a semi-classical method
based on multipolar and atom-atom interaction potentials. The temporal evolutions of the
populations of the
(
v=(100) or (001)) levels, calculated by our model,
show a strong dependence on the value of the
number. The predicted temperature
dependence of the energy transfers from (100) levels towards (001) levels, after pumping into a
(100) level, agrees well with the available results obtained from double- resonance experiments in
the 200-300 K temperature range.
