Xiang, L. Zhu Title: Absorption cross sections of E,E-2,4-hexadienedial at 248 nm, and in the 290–430 nm region, and photolysis study at 248, 308, and 351 nm Journal/Source: Chem. Phys. Lett., 450, 31-38, (2007); doi:10.1016/j.cplett.2007.11.010 Data: diagram, table Energy/Wavelength range: 248 nm; 290 - 430 nm Resolution: Temperature: 295 K Temperature dependence: no Pressure/Concentration: Phase: vapor pH: Comments: The HCO product channel following 248, 308, and 351 nm photolysis of E,E-2,4-hexadienedial was examined. The HCO radical was only observed at 248 nm, with quantum yield of 0.014 (absolute uncertainty in HCO yield is ~ 86%). Author to whom correspondence should be addressed: (e-mail address):
