science-softCon uv/vis spectra data base; www.uv-spectra.de; (C) science-softCon 2008 Substance: cyanoacetylene Other Names: propiolonitrile Formula: C3HN CAS-No.: 1070-71-9 Study: photochemistry, absorption spectrum, quantum yields Authors: J. A. Halpern, G. E. Miller, H. Okabe, W. Nottingham Title: The UV photochemistry of cyanoacetylene Journal/Source: J. Photochem. Photobiol. A: Chem., 42, 63-72, (1988); doi:10.1016/1010-6030(88)80049-2 Data: (diagram, table, disk): Energy/Wavelenght range: 188 - 240 nm Resolution: Temperature: Temperature dependence: Pressure: Comments: The absorption cross-section of HC3N between 240 and 188 nm has been measured. The quantum yield for the process HC3N + hv --> C2H + CN at 193 nm is found to be about 0.05. These experiments point to HC3N + hv --> H + C3N as the major process in the UV photolysis of cyanoacetylene. Author to whom correspondence should be addressed: (e-mail address):
