✦ Synopsis

The spectra of ozone in the region (2300-2600 \mathrm{~cm}^{-1}) have been recorded with the high-resolution Fourier transform spectrometer of Reims. A White-type cell with a length of (36 \mathrm{~m}) and pressure of (50 \mathrm{Torr}) of ozone has been used. This region corresponds mainly to the weak bands (v_{1}+2 v_{2}) and (2 \nu_{2}+\nu_{3}), which were previously analyzed with a much lower amount of ozone. Now high values of (J) and (K_{a}) have been observed up to 55 and 11 , respectively. The final fit on the 615 energy levels is very satisfactory, (0.39 \times 10^{-3} \mathrm{~cm}^{-1}), equal to experimental accuracy. Good agreement is also obtained for line intensities. Furthermore, the two difference bands (3 \nu_{3}-\nu_{2}) and (\nu_{1}) (+2 \nu_{3}-\nu_{2}) have been observed for the first time and their transition moments are given. (c) 1995 Academic Press, Inc.
