Using a high-pressure \(\times\) path length sample of ozone it has been possible to record at high resolution ( \(0.006 \mathrm{~cm}^{-1}\) ) the \(3-\mu \mathrm{m}\) absorption region of this molecule. A thorough analysis of the spectra has been performed allowing one to assign for the first time

The infrared spectra of 16 O 3 have been recorded in the 3700 cm 01 region, with a Fourier transform spectrometer at 0.008 cm 01 resolution. A White-type cell, ᐉ Å 32.16 m, filled with 42.8 Torr O 3 was used. This spectral region corresponds to the n 2 / 3n 3 and n 1 / n 2 / 2n 3 bands. The n 2 / 3n
New measurements are reported for the infrared spectrum of sulfur trioxide, 32 S 16 O 3 , with resolutions ranging from 0.0015 cm -1 to 0.0025 cm -1 . Rovibrational constants have been measured for the fundamentals ν 2 , ν 3 , and ν 4 and the overtone band 2ν 3 . Comparisons are made with the earlie
Further analysis of the high-resolution (0.0015 cm -1 ) infrared spectrum of 32 S 16 O 3 has led to the assignment of more than 3100 hot band transitions from the ν 2 and ν 4 levels to the states 2ν 2 (l = 0), ν 2 + ν 4 (l = ±1), and 2ν 4 (l = 0, ±2). These levels are strongly coupled via Fermi reso
