science-softCon uv/vis spectra data base; www.uv-spectra.de; (C) science-softcon 2008 Substance: ethyne Other Names: acetylene Formula: C2H2 CAS-No.: 74-86-2 Study: photochemistry Authors: H. Okabe Title: Photochemistry of acetylene at 1470 A Journal: J. Chem. Phys. 75, 2772, (1981); DOI:10.1063/1.442348 Data: (diagram, table, disk): Wavelength range: 147.0 nm Resolution: Temperature: Temperature dependence: Pressure: 0.1–10 Torr Comments: The quantum yield of diacetylene formation has been measured as a function of C2H2 pressure and the partial pressures of He and N2. Absorption cross sections of diacetylene have been measured in the 1200 and 1800 Å region. Author to whom correspondence should be addressed: (e-mail address):
