DATAFILE: CH3I_Pence(1981)_295K_248,308nm.txt
NAME: iodomethane, methyl iodide
AUTHOR(YEAR): Pence(1981)
T: 295K
λ: 248,308nm
BIBLIOGRAPHY: W.H. Pence, S.L. Baughcum, and S.R. Leone, "Laser UV photofragmentation of halogenated molecules. Selective bond dissociation and wavelength-specific quantum yields for excited I(2P1/2) and Br(2P1/2) atoms", J. Phys. Chem. 85, 3844-3851 (1981); DOI: 10.1021/j150625a027
COMMENTS: Absorption measurements at 185-400 nm; spectrum reported as a plot with arbitrary absorbance units vs. wavelength in Fig. 3

Extinction coefficients at selected laser wavelengths from Table I were converted to absorption cross sections (conversion factor 3.8235×10-21)
