COMMENTS: Absorption measurements at a spectral resolution of 0.11 nm using a flow gas cell and a D2 lamp as a light source

Absorption cross sections obtained by Clara Sousa-Silva for the "extrapolation prescription", i.e. replacing the measured data at wavelengths above 205 nm with a theoretical extrapolation corresponding to a log-linear loss of absorption towards dissociation (one of two presciptions for the absorption cross sections for incorporation into the author's photochemical models; corrected for Rayleigh scattering)

Data have been obtained by personal communication from Sukrit Ranjan (May 2020)
