Title: Temperature dependence of the NO3 absorption cross-section above 298 K and determination of the equilibrium 
constant for NO3 + NO2  <--> N2O5 at atmospherically relevant conditions

Journal: Phys. Chem. Chem. Phys., 9, 5785-5793, (2007), DOI: 10.1039/b709193a


Data: (diagram, table, disk): table

Wavelength range: 662 nm

Resolution: 

Temperature: 298 - 388 K

Temperature dependence: yes

Comments: New data for the peak cross section (662.2 nm, vacuum wavelength) were combined with previous measurements 
in the 200 K–298 K region. A least-squares fit to the combined data gave sigma = [(4.582 +- 0.096) – (0.00796 +- 0.00031) × T] × 10-17 cm2 molecule–1.
