The results of the highly sensitive recording of the absorption spectrum for the Wulf band series in the near-infrared range 9350–10 000 cm–1, corresponding to the transitions from the ground to an excited triplet electronic state of the ozone molecule, are discussed. For the first time, the ozone spectrum in the range above the main molecular dissociation threshold was recorded using a continuous wave cavity ring-down spectrometer (cw-CRDS). The spectrometer provided sensitivity on the order of 1 × 10–10 cm–1 for the absorption coefficient. The measurement technique, ozone generation, and control of its concentration are described. A comparison with previously calculated theoretical spectra of the singlet-triplet bands 3A2(000) ← X 1A1(000), 3A2(010) ← X 1A1(000), and 3A2(010) ← X 1A1(010) is carried out.
