Sangwan, L. Zhu Title: Absorption Cross Sections of 2-Nitrophenol in the 295-400 nm Region, and Photolysis of 2-Nitrophenol at 308 and 351 nm Journal/Source: J. Phys. Chem., A, 120 (50), 9958-9967, (2016); DOI: 10.1021/acs.jpca.6b08961 Data: table, diagram Energy/Wavelength range: 295 - 400 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: pressure range varied between 5.0 x 10-4 and 1.5 x 10-2 Torr Phase: gas pH: Comments: 2-Nitrophenol shows a broad absorption band over the wavelength region studied in this investigation. The peak absorption is located at 345 nm. Within the 295-400 nm range, the absorption cross section values range between (2.86 ± 0.18) x 10-18 and (2.63 ± 0.31) x 10-20 cm2/molecule. The measured average HONO quantum yields are 0.34 ± 0.09 and 0.39 ± 0.07 at 308 and 351 nm. Author to whom correspondence should be addressed: (e-mail address):
