| COMMENTS: | The cross section at 185 nm was derived relative to cross sections at 248 and 266 nm; this was achieved by passing a constant flow of phosgene through the 185 nm extinction optical cell and then through a multi-pass optical set-up (l = 892 cm) equipped with a diode array spectrometer to obtain simultaneous extinction (and thus relative cross sections) at 185, 248 and 266 nm The relative cross sections were then normalized to the well-known cross section of phosgene at 248 nm from the IUPAC evaluation, R.

Phys. 8, 4141-4496 (2008), to derive the effective cross section at 185 nm |
