Foreman, K.M. Kapnas, YiTien Jou, J. Kalinowski, D. Feng, R.B. Gerber, C. Murray Title: High resolution absolute absorption cross sections of the B1A'-X1A' transition of the CH2OO biradical Journal/Source: Phys. Chem. Chem. Phys., 17, 32539-32546, (2015); DOI: 10.1039/C5CP04977F Data: table, diagram Energy/Wavelength range: 362 - 470 nm Resolution: 0.12 nm Temperature: 298 K Temperature dependence: no Pressure/Concentration: 50 torr (total pressure comprising 0.01% CH2I2, 7.3% O2 and N2 balance) Phase: gas pH: Comments: The absolute absorption cross sections over the 362-470 nm range are in good agreement with those reported by Ting et al. Broadband absorption spectra recorded over the temperature range of 276-357 K were identical within their mutual uncertainties, confirming that the vibrational structure is not due to hot bands.
