The b(1)Sigma(g)(+)-X(3)Sigma(g)(-) (2,0) band of the O-16(2), (OO)-O-16-O-17, O-17(2) and O-18(2) oxygen isotopomers was investigated by means of cavity-ring-down laser spectroscopy. Line positions of the four branches in each band were determined with an accuracy of 0.01 cm(-1). Improved or new molecular constants are derived for the b(1)Sigma(g)(+), v = 2 excited state of the four isotopomers. (C) 1999 Elsevier Science B.V. All rights reserved.
