science-softCon uv/vis spectra data base; www.uv-spectra.de Substance: acetaldehyde Other Names: ethanal Formula: C2H4O CAS-No.: 75-07-0 Study: photolysis, quantum yield Authors: Yongxin Tang, Lei Zhu, Liang T. Chu, Bin Xiang Title: Cavity ring-down spectroscopic study of acetaldehyde photolysis in the gas phase, on aluminum surfaces, and on ice films Journal: Chem. Phys., 330, 155-165, (2006); doi:10.1016/j.chemphys.2006.08.005 Data: (diagram, table, disk): Wavelength range: 308 nm Resolution: Temperature: 243 K, 293 K Temperature dependence: Comments: The HCO radical quantum yields from the gas-phase photolysis of acetaldehyde are 0.87 +- 0.11 and 0.91 +- 0.10 at 243 and at 293 K, respectively, where errors quoted represent 1sigma measurement uncertainty.
