science-softCon uv/vis+ spectra data base; www.uv-spectra.de; (C) science-softCon 2010 Substance: methyl radical Other Names: Formula: CH3 CAS-No.: 2229-07-4 Study: uv absorption cross sections Authors: M. T. Macpherson, M. J. Pilling, M. J. C. Smith Title: Determination of the absorption cross section for methyl at 216.36 nm and the absolute rate constant for methyl radical recombination over the temperature range 296-577 K Journal/Source: J. Phys. Chem., 89 (11), 2268-2274, (1985); DOI: 10.1021/j100257a024 Data: (diagram, table, disk): EnergyWavelength range: 216.36 nm Resolution: 0.6 nm Temperature: 298 K; 298 - 537 K Temperature dependence: Pressure/Concentration: Phase (gas, liquid, solid): pH: Comments: Two different measurement methods are used to determine the absorption cross section of CH3 at 216.36 nm. The two room temperature determinations gave cross sections in good agreement (4.12 ± 0.24) x 10-17 cm2 and (4.01 ± 0.26) x 10-17 cm2.
