COMMENTS: Recommended absorption cross section at the Lyman-α wavelength with an estimated uncertainty factor p(298 K) = 1.3

The value is taken from the absorption spectrum reported by

R. Locht, B. Leyh, H.W. Jochims, and H. Baumgärtel, "The vacuum UV photoabsorption spectrum of methyl bromide (CH3Br) and its perdeuterated isotopomer CD3Br: a Rydberg series analysis", Chem. Phys. 317, 73-86 (2005); DOI: 10.1016/j.chemphys.2005.06.002
