Alain Barbe, Marie-Renée De Backer-Barilly, Vladimir G. Tyuterev, and Serguei A. Tashkun, "Observations of infrared bands of asymmetrical ozone isotopologues 16O16O18O and 16O18O18O," Appl. Opt. 42, 5136-5139 (2003)
Infrared spectra (0.003 cm-1 resolution) of 16O16O18O and 16O18O18O ozone isotopologues have been recorded and analyzed in the range 600–5000 cm-1. Several thousand rovibrational lines belonging to 32 absorption bands have been measured and assigned. An accurate determination of band centers through the rovibrational analysis has been done, 12 bands being observed for the first time to our knowledge. In addition to atmospheric retrieval applications, these results are also useful for a validation of potential energy surfaces and for the study of isotope effects in dynamic processes of ozone.
