NAME: acetylene, ethyne
FORMULA: C2H2
AUTHOR(YEAR): Gardiner(1987)
T: 1100-2900K
λ: 214nm
BIBLIOGRAPHY: W.C. Gardiner, Jr., S.M. Hwang, and R. M.J. Rabinowitz, "Shock tube and modeling study of methyl radical in methane oxidation", Energy Fuels 1, 545-549 (1987) DOI: 10.1021/ef00006a016
COMMENTS: Absorption measurements in shock-heated acetylene/argon mixtures using light from a Zinc Pen-Ray lamp directed into a monochromator set at 214 nm

Least-squares fit for the extinction coefficient

ε (in cm2/mol) = 7.81×106 exp(-10400/T) + 2.21×105 exp(-2050/T)

converted to absorption cross sections (conversion factor 3.8235×10-24)
