Abstract:
Symmetry selective detection of the 17O containing ozone isotopomers 16O16O17O and 16O17O16O
requires the unambiguous identification of absorption lines.We report high resolution tuneable diode
laser spectrometer measurements of 17O containing ozone isotopomers in the R-branch of the υ3 band
and present a purely experimental technique that discriminates between 16O16O17O and 16O17O16O.
Around 1040 cm-1, differences in line positions of 16O17O16O upto 4×10-3 cm-1 between our
measurements and present spectroscopic database records (HITRAN 2004) are found.
