Low temperature mid-infrared cross-sections for peroxyacetyl nitrate (PAN) vapour

. Laboratory absorption spectra of peroxyacetyl nitrate (PAN, CH3C(O)OONO2) vapour have been measured in the mid-infrared range 550 cm-1 to 1400 cm-1 (18.2 to 7.14 µm) at both 250 K and 273 K, using a Fourier transform infrared spectrometer at a nominal spectral resolution of 0.25 cm-1 (unapodised). In addition, the 1600 cm-1 to 2200 cm-1 (6.25 to 4.54 µm) spectral region has been measured at 250 K. Cross-sectional data at each temperature, as...
