1 January 1996 Infrared absorption of O3 under CO2 laser excitation

A homemade TEA CO2 multimode line-tunable laser was used as a radiation source to study the IR absorption of O3 in pure samples and in O3-M mixtures (M= O2, N2, and air) at the initial steps of the excitation by direct calorimetric measurements. The fluence and pressure dependence of the O3 absorption cross section o and the number of photons absorbed (n) were determined for all the available rotational lines P(4) through P(58) of the 9.5-µm emission band. The dependence of (n) on added nonreactive gas pressure over the range O to 750 Torr was studied for three different fluences of the P(30) line.
