T: 293K
λ: 185.630-236.290nm
BIBLIOGRAPHY: Y. Bénilan, N. Smith, A. Jolly, and F. Raulin, "The long wavelength range temperature variations of the mid-UV acetylene absorption coefficient", Planet. Space Sci. 48, 463-471 (2000); DOI: 10.1016/S0032-0633(00)00019-2

Absorption measurements with a spectral resolution of 0.02 nm using a D2 lamp as a light source

Data at intervals of 0.007 nm have been downloaded from "Titan's spectroscopic database"
New version:

Absorption coefficients in cm-1 amagat-1 (base e) have been converted to absorption cross sections (conversion factor 3.72×10-20)
