Troe, "Evaluated kinetic and photochemical data for atmospheric chemistry: Volume III - gas phase reactions of inorganic halogens", Atmos. Chem. Phys. 7, 981-1191 (2007); DOI: 10.5194/acp-7-981-2007
COMMENTS: IUPAC (2007) recommendation:

The preferred values of the absorption cross-sections at 298 K are the values calculated with the expression given by

R.J. Barnes, A. Sinha, and H.A. Michelsen, "Assessing the contribution of the lowest triplet state to the near-UV absorption spectrum of HOCl," J. Phys. Chem. A 102, 8855-8859 (1998); DOI: 10.1021/jp9835869,

based on their data from the laser induced fluorescence of HO and on the data of

J.B. Burkholder, "Ultraviolet absorption spectrum of HOCl," J. Geophys. Res. 98(D2), 2963-2974 (1993); DOI: 10.1029/92JD02522
