COMMENTS: IUPAC(2015) recommendation:

the absorption cross sections have been calculated using the Gaussian fit

σ(λ) = 1.25316 × 10-17 × exp [-0.000460967 × (328.28 - λ)2]

to the data of

M.C. Smith, W.-L. Ting, C.-H. Chang, K. Takahashi, K.A. Kristie A. Boering, and J.J.-M. Lin, "UV absorption spectrum of the C2 Criegee intermediate CH3HOO," J. Chem. Phys. 141, 074302-1 - 074302-7 (2014);

The listed "preferred values" are erroneous (those of CH2OO)
