Abstract:	Absolute absorbance cross sections for OClO were measured between 125 and 470 nm using a 0.5 m vacuum monochrometer and a PMT detector. In all, 26 primary symmetric stretching bands and 24 combination bending and asymmetric stretching bands of the A 2A2 system were observed between 260 and 460 nm. Four additional band systems were also observed in the vacuum UV region between 125 and 190 nm. Cross sections were measured for three symmetric stretch C bands ( 183.08, 179.8 5 and 176.77 nm), nine symmetric stretch (162.66, 160.08, and 155.01 nm), asymmetric stretch (I 57.27 and 154.68 nm) and bending (I 61.38, 158.55, and 15 5.90 nm) D bands, seven bending E bands (156.7 5, 15 5.48, 154.30, 15 3.11, 151.99, 150.90, and 149.83 nm) and twenty-one F bands ( 144.29, 143.29, 142.17, 140.87, 139.78, 139.00, 138.00, 137.24, 136.22, 135.22, 134.38, 133.83, 133.20, 132.78, 132.06, 131.13, 130.61, 130.00, 128.51, 127.78, and 127.00 nm). In addition, a cross sectional minimum of 4 X 10(-20) cm2 molecule-1 was found between the A 2A2 system and the C system near 248 nm. Finally, the observed C, D, E, and F states were analyzed in terms of Rydberg progressions leading to the first and second ionization potentials and allowed prediction of some relative energy levels in the ground state and in excited states.
