Title: UV absorption cross sections of HO2NO2 between 343 and 273 K

Journal/Source: Phys. Chem. Chem. Phys., 4, 1432-1437, (2002); doi: 10.1039/B108904H


Data: 

Energy/Wavelength range: 280 - 350 nm

Resolution: ~ 1.5 nm

Temperature: 273 K, 296 K, 318 K, 343 K

Temperature dependence: yes

Pressure/Concentration:

Phase: gas

pH:


Comments: The PNA spectra were placed on an absolute scale by using previously determined absolute cross sections 
over the wavelength range 250–270 nm. The temperature dependence of the cross section data has been parametrized 
over this temperature range using a semi-empirical two-level model.
