Unambiguous identification of (17)O containing ozone isotopomers for symmetry selective detection.

Symmetry selective detection of the (17)O containing ozone isotopomers (16)O(16)O(17)O and (16)O(17)O(16)O requires the unambiguous identification of absorption lines. We report high resolution tuneable diode laser spectrometer measurements of (17)O containing ozone isotopomers in the R-branch of the nu3 band and present a purely experimental technique that discriminates between (16)O(16)O(17)O and (16)O(17)O(16)O. Around 1040 cm(-1), differences in line positions of (16)O(17)O(16)O upto 4 x 10(-3) cm(-1) between our measurements and present spectroscopic database records (HITRAN 2004) are found.
