Kahan, R.A. Washenfelder, V. Vaida, S.S. Brown Title: Cavity-Enhanced Measurements of Hydrogen Peroxide Absorption Cross Sections from 353 to 410 nm Journal/Source: J. Phys. Chem. A, 116 (24), 5941-5947, (2012); DOI: 10.1021/jp2104616 Data: table, diagram Energy/Wavelength range: 353 - 410 nm Resolution: ~ 0.116 nm Temperature: 297 K Temperature dependence: no Pressure/Concentration: 850 hPa Phase: gas pH: Comments: Near-ultraviolet and visible absorption cross sections of hydrogen peroxide (H2O2) using incoherent broad-band cavity-enhanced absorption spectroscopy (IBBCEAS) are reported. The measurements reported here span the range of 353-410 nm and extend published electronic absorption cross sections by 60 nm to absorption cross sections below 1 × 10-23 cm2 molecule-1.
