摘要：

High resolution spectra (0.014 cm(-1)) of O-3 of the highly structured first two members of the Wulf progression in the near-infrared spectral range (9100-10200 cm(-1)) have been measured by intracavity laser absorption spectroscopy (ICLAS). A preliminary analysis of the rotational structure confirmed previous assignments for the lowest excited (3)A(2) (triplet) state. However, the linewidths of the (3)A(2) --> (1)A(1) transitions have been found to be considerably broadend depending upon the J and K rotational quantum number, as well vibrational excitation. The short lifetimes inferred from these linewidths suggest that the rovibrational states of ozone's lowest triplet state are predissociative and not ''metastable''. (C) 1997 Elsevier Science B.V.
