COMMENTS: Absorption measurements in shock-heated methyl iodide as a methyl precursor using narrow-line laser radiation

Absorption coefficients k (atm-1 cm-1) (base e) plotted in Fig.1 have been digitized and converted to absorption cross sections sections (conversion factor RT = 1.36×10-22 T; R (gas constant) in cm3 atm molecule-1 K-1)
