✦ Synopsis

Vibrational spectra of 16 O/ 17 O/ 18 O enriched ozone have been recorded both in argon and nitrogen matrices using Fourier transform spectroscopy. The fundamental bands n 1 , n 2 , and n 3 as well as the combination band n 1 / n 3 have been analyzed from two mixtures with different isotopic abundances. Most of the observed absorption peaks were assigned, and a change in the relative intensities of the three fundamental modes was evidenced for unsymmetrical isotopic species. The present investigation has been undertaken to better understand possible mechanisms of isotopic enhancements observed in the stratosphere.
