COMMENTS: Absorption cross sections for the A 1A2 ← X 1A1 electronic transition

The absorption cross sections for the regions

302.546-312.015nm,
313.260-319.667 nm,
325.114-332.882 nm

are a convolution of the high-resolution spectrum with a Gaussian function of FWHM 0.2 nm and have been downloaded from the "Supporting Information" published along with the online version of the article
