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.
