Atomic Versus Molecular Elimination in Halogenated Hydrocarbons

Atomic versus Molecular Elimination in Halogenated Hydrocarbons 

The translational energy probability P(E ), obtained from TOF measurements of the Br atom from HC2CH2Br at 193 nm shows two peaks at 30 and 120 kJ/mol. The fast Br atoms are thought to come from excitation of the a orbital on the Br atom via the process 

HBr is also observed in the photodissociation of this compound, and it is thought to arise along with slow Br atoms from an 

The peaks of the P(E ) curves occur at an ET of 240, 150, and 140 kJ/mol for reactions 73, 74, and 75, respectively. In addition to reaction 74, the ethyl chloride molecule also yields and C2H4 and HCI molecule via reaction 76. 

The peak of the P(E ) for this reaction occurs at 20 kJ/mol, similar to the other reactions of this type.
