Ting, Y.-H. Chen, W. Chao, M. C. Smith, J. Jr-Min Lin Title: The UV absorption spectrum of the simplest Criegee intermediate CH2OO Journal/Source: Phys. Chem. Chem. Phys.,16, 10438-10443, (2014); DOI: 10.1039/C4CP00877D Data: table, diagram Energy/Wavelength range: 280 - 484 nm Resolution: 0.6 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: 8 - 100 Torr (total pressure) Phase: gas pH: Comments: Absolute absorption cross sections of CH2OO at 308.4 and 351.8 nm were obtained from laser-depletion measurements in a jet-cooled molecular beam. The peak cross section is (1.23 ± 0.18) x 10^-17 cm2/molecule) at 340 nm. The estimated relative error is about 12% for 280 - 290 nm, 9% for 290 - 300 nm, 7% for 300 - 310 nm, <5% for 310 - 484 nm.
