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 the (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 760 nm were observed using cavity-ring-down absorption spectroscopy. The positions of over 340 lines are presented together with (re-) analyses of the rotational constants. We discuss the importance of these data in view of tests of the symmetrization postulate in O-16(2) and present a sensitivity scale of 13 orders of magnitude that could be practical for future test experiments.
