DATAFILE: ClOOCl_Burkholder(1990)_250K_212-404nm.txt
NAME: dichlorine dioxide, chlorine monoxide dimer, chlorine peroxide
FORMULA: ClOOCl
AUTHOR(YEAR): Burkholder(1990)
T: 250K
λ: 212-404nm
BIBLIOGRAPHY: J.B. Burkholder, J.J. Orlando, and C.J. Howard, "Ultraviolet absorption cross section of Cl2O2 between 210 and 410 nm", J. Phys. Chem. 94, 687-695 (1990); DOI: 10.1021/j100365a033
COMMENTS: A discharge flow tube reactor coupled to a to a multipass absorption cell and a diode array spectrometer (spectral resolution ∼1.2 nm)

The transient CI2O2 molecule was produced by using the gas-phase reaction CIO + CIO + M → Cl2O2 + M, and three independent CIO radical source reactions, CI + O3, CI + CI2O, and CI + OCIO were used

The absorption spectrum depicted in Fig. 5 has been digitized
