DATAFILE: ClOOCl(not,ratherCl2O3)_MolinaMolina(1987)_240K_200-346nm.txt
NAME: dichlorine dioxide or dichlorine trioxide
FORMULA: ClOOCl(not,ratherCl2O3)
AUTHOR(YEAR): MolinaMolina(1987)
T: 240K
λ: 200-346nm
BIBLIOGRAPHY: L.T. Molina and M.J. Molina, "Production of Cl2O2 from the self-reaction of the ClO radical", J. Phys. Chem. 91, 433-436 (1987); DOI: 10.1021/j100286a035
COMMENTS: Reaction of Cl atoms with one of three different ClO precursors: O3, Cl2O, or OClO and absorption measurements using a double beam spectrophotometer

The spectrum has been assigned to ClOOCl, but later identified as Cl2O3, see e.g.

M.H. Harwood, D.M. Rowley, R.A. Freshwater, R.A. Cox, and R.L. Jones, "A spectroscopic study of Cl2O3," J. Chem. Soc. Faraday Trans. 91, 3027-3032 (1995); DOI: 10.1039/FT9959103027
