B(1)SIGMA(G)(-X-3-SIGMA(G)(-) (0,0)-BAND OF OXYGEN ISOTOPOMERS IN RELATION TO TESTS OF THE SYMMETRIZATION POSTULATE IN O-16(2)())

We investigated the b (1) Sigma(g)(+)-X-3 Sigma(g)(-) (0,0) band of th e (OO)-O-16-O-18, (OO)-O-16-O-17, O-18(2), (OO)-O-17-O-18, and O-17(2) isotopomers of oxygen. The weak magnetic dipole transitions around 76 0 nm were observed using cavity-ring-down absorption spectroscopy. The positions of over 340 lines are presented together with (re-) analyse s of the rotational constants. We discuss the importance of these data in view of tests of the symmetrization postulate in O-16(2) and prese nt a sensitivity scale of 13 orders of magnitude that could be practic al for future test experiments.
