NAME: chlorine dioxide
FORMULA: OClO
AUTHOR(YEAR): HubingerNee(1994)
T: 298K
λ: 363.38-401.89nm(A-X (IV))
BIBLIOGRAPHY: S. Hubinger and J.B. Nee, "Photoabsorption spectrum for OClO between 125 and 470 nm", Chem. Phys. 181, 247-257 (1994); DOI: 10.1016/0301-0104(94)85027-5
COMMENTS: Absorption measurements in a a flow cell using a vacuum monochromator, deuterium lamps or a krypton microwave discharge continuum as light sources and photomultiplier sensitive either in the UV/nearUV or in the vacuum UV

A ← X system:

Band heads of the vibrational progression v'1 = 8 - 4, v'2 = 1, v'3 = 2 (symmetric, asymmetric stretch and bending)

Fig. 2 shows the A-X band at 240-460 nm, Fig. 1 shows the entire spectrum at 100-500 nm
