DATAFILE: N2O5_Harwood(1993)_253K_240-410nm.txt
NAME: dinitrogen pentoxide
FORMULA: N2O5
AUTHOR(YEAR): Harwood(1993)
T: 253K
λ: 240-410nm
BIBLIOGRAPHY: M.H. Harwood, R.L. Jones, R.A. Cox, E. Lutman, and O.V. Rattigan, "Temperature-dependent absorption cross sections of N2O5", J. Photochem. Photobiol. A: Chem. 73, 167-175 (1993); DOI: 10.1016/1010-6030(93)90001-2
COMMENTS: Measurements over the temperature range 233-313 K using a dual beam diode array spectrometer; spectral resolution 1.3 nm (FWHM).

The temperature dependence of the absorption cross sections at each wavelength was parameterized by the function

log10 σ (cm2 molecule-1) = A + 1000B/T resulting in the temperature coefficients
