NAME: acetylene, ethyne
FORMULA: C2H2
AUTHOR(YEAR): Cooper(1988)
T: 298K
λ: 6.9-206.6nm(e,e)
BIBLIOGRAPHY: G. Cooper, T. Ibuki, Y. Iida, and C.E. Brion, "Absolute dipole oscillator-strengths for photoabsorption and the molecular and dissociative photoionization of acetylene", Chem. Phys. 125, 307-320 (1988); DOI: 10.1016/0301-0104(88)87085-X
COMMENTS: HC≡CH

Measured by dipole (e,e) spectroscopy; energies E (in eV) and differential oscillator strengths df/dE (in 10-2 eV-1) converted to wavelengths and absorption cross sections,
σ (in 10-18 cm2 molecule-1) = 109.75 df/dE (in eV-1)
