The relaxation of ozone excited into the (101) vibrational state is studied in O-3-O-2 and O-3-N-2 gas mixtures over the 200-300 K temperature range using a laser double-resonance (DR) technique. Rate coefficients for V-V transfer processes occurring in O-3-O-3 collisions are experimentally determined and theoretically calculated. The temperature exponent n obtained by fitting the calculated values with a law of the form k(T) = k(T-0)(T-0/T)(n) is in very good agreement with the experimental values. To model the vibrational energy deactivation processes occurring upon O-3-foreign gas collisions, the rate coefficients for levels higher than the first dyad are deduced from the rate coefficients for the lowest states using simple scaling. The simulated DR signals obtained by a kinetic model using these values are in good agreement with the corresponding experimental DR signals over the entire temperature range.
