Electronically excited ozone (O3*) was produced in the gas phase by flash irradiation using a dye-pumped flash system employing Rhodamine 6G as the converter dye. Kinetic studies of the decay of the u.v. absorption transient due to O3*, were made by monitoring the enhanced absorption at its peak wavelength of 320 nm. The results are consistent with a mechanism involving poor quenching by bimolecular collisions but effective quenching at the cell walls, and yield a radiative lifetime for O3* (previously assigned as the 1A2 state) of 4.10 +/- 0.95 ms. An alternative interpretation of the data in terms of rapid degradation of electronic to vibrational excitation followed by bulk heating of the gas is discussed and shown to be implausible. An upper limit on the quenching rate coefficients for O3* collisions with O3 and He can be set at <= 10-18 cm 3 molecule -1s-1.
