NAME: acetylene, ethyne
AUTHOR(YEAR): NakayamaWatanabe(1964)
T: 298K
λ: 100-155nm
BIBLIOGRAPHY: T. Nakayama and K. Watanabe, "Absorption and photoionization coefficients of acetylene, propyne, and 1-butyne", J. Chem. Phys. 40, 558-561 (1964); DOI: 10.1063/1.1725154

Absorption measurements at a resolution of 0.1 nm using a windowless hydrogen discharge tube as a light source

Absorption coefficients k (atm, 273 K)-1 cm-1 (base e) depicted in Fig. 1 have been digitized and converted to absorption cross sections (conversion factor 3.72×10-20)
