BIBLIOGRAPHY: K. Glänzer, M. Quack, and J. Troe, "High temperature UV absorption and recombination of methyl radicals in shock waves (Proceedings of the 16th Symposium (International) on Combustion, Pittsburgh)", Proc. Combust. Inst. 16, 949-960 (1977); DOI: 10.1016/S0082-0784(77)80387-1
COMMENTS: Absorption measurements in shock-heated azomethane-argon mixtures as methyl precursor

The temperature dependence of the decadic molar extinction coefficient at 216 nm is shown in Fig, 8 by

Takao Tsuboi, Japan. J. Appl. Phys. 17, 709-716 (1978)

Extinction coefficients in cm2/mol plotted in Fig. 8 have been digitized and converted to absorption cross sections (conversion factor 3.8235×10-24)
