HIGH-RESOLUTION INFRARED-SPECTRA OF OZONE IN THE 2300-2600 CM(-1) REGION

The spectra of ozone in the region 2300-2600 cm(-1) have been recorded with the high-resolution Fourier transform spectrometer of Reims. A W hite-type cell with a length of 36 m and pressure of 50 Torr of ozone has been used. This region corresponds mainly to the weak bands nu(1) + 2 nu(2) and 2 nu(2) + nu(3), which were previously analyzed with a m uch lower amount of ozone. Now high values of J and K-a have been obse rved up to 55 and 11, respectively. The final fit on the 615 energy le vels is very satisfactory, 0.39 X 10(-3) cm-l, equal to experimental a ccuracy. Good agreement is also obtained for line intensities. Further more, the two difference bands 3 nu(3) - nu(2) and nu(1) + 2 nu(3) - n u(2) have been observed for the first time and their transition moment s are given. (C) 1995 Academic Press, Inc.
