Article abstract of DOI:10.1021/j150618a025

C2H5I was photolized at 313 nm and 22 deg C in the presence of either I2, (C2H5)2NOH, or O2-He mixtures.We have determined that the quantum yields for the primary processes C2H5I + hυ -> C2H5 + I (3a) and C2H5I + hυ -> C2H4 + HI (3b) are Φ_3a = 0.31 +/- 0.01 and Φ_3b = 0.0095 +/- 0.0005.An upper limit for the rate coefficient for the following reaction has been found to be 1 x 1E-14 cm³/(molecule s) at 22 deg C: C2H5 + O2 -> C2H4 + HO2 (1).
