DATAFILE: CF3O2NO2_Malanca(2005)_300K_200-340nm.txt
NAME: trifluoromethyl peroxynitrate
FORMULA: CF3O2NO2
AUTHOR(YEAR): Malanca(2005)
T: 300K
λ: 200-340nm
BIBLIOGRAPHY: F.E. Malanca, M.S. Chiappero, G.A. Argüello, and T.J. Wallington, "Trifluoro methyl peroxynitrate (CF3OONO2): Temperature dependence of the UV absorption spectrum and atmospheric implications", Atmos. Environ. 39, 5051-5057 (2005); DOI: 10.1016/j.atmosenv.2005.05.026
COMMENTS: Averages over 5-nm intervals of the spectrum recorded at a resolution of 1 nm using a diode array spectrometer.
The error limits of the absorption cross sections are listed in the third column of the datafile

The representation of log σ vs. T leads to linear fits according to

log10 σ(T) = B × T + log10 σ(0 K).

The intercepts σ(0 K) and slopes B at selected wavelengths are as follows (standard deviations of B in brackets):

---------------------------------------------------
λ  103 B   1020 σ(0 K)
(nm) (K-1)   (cm2 molecule-1)
---------------------------------------------------
290 6.8 (0.2)  1.2×10-2
295 8.3 (0.9)  2.9×10-3
300 10.5 (0.6)   4.4×10-4
305 12 (1)    8.4×10-5
310 14 (1)    1.9×10-6
315 16.4 (0.9)  2.9×10-6
320 18 (2)    6.0×10-7
