COMMENTS: Absorption measuremnts in shock heated acetylene/argon mixtures

Absorption coefficients k (atm-1 cm-1) (base e) vs. temperature as plotted in Fig. 11 have been digitized and converted to absorption cross sections (conversion factor RT = 1.36×10-22 T; R (gas constant) in cm3 atm molecule-1 K-1)
