Brownsword, P. Schmiechen, H.-R. Volpp, H.P. Upadhyaya, Y.J. Jung, K.-H. Jung Title: Chlorine atom formation dynamics in the dissociation of CH3CF2Cl (HCFC-142b) after UV laser photoexcitation Journal/Source: J. Chem. Phys., 110, 11823-11829, (1999); https://doi.org/10.1063/1.479124 Data: diagram, table Energy/Wavelength range: 193.3 nm Resolution: Temperature: 298 K Temperature dependence: no Pressure/Concentration: Phase: pH: Comments: The absolute quantum yields for photolytic formation of Cl* and Cl atoms were determined to be PHI (Cl + Cl*) = 0.90 +- 0.17. The [Cl*]/[Cl] branching ratio is 0.39 +- 0.11. Author to whom correspondence should be addressed: (e-mail address):
