PRESSURE SHIFTS OF O3 BROADENED BY N2 AND O2

High resolution infrared spectra of O3 have been recorded with an FT spectrometer at Reims University with a resolution of 0.002 cm-1 and a SNR of the order of 800. The 2100-cm-1 region corresponding to the nu-1 + nu-3 band has been analyzed. A large number of spectra, with ozone pressure varying from 5 to 50 Torr and foreign gas from 80 to 700 Torr, were recorded. The CO lines were recorded simultaneously and used as the standard to obtain the shifts, which have been measured for about 150 lines. We note a linear variation of the shifts with the J quantum number.
