Kinetic study of the photochlorination of 2,3-dimethylbutane and other alkanes in solution in the presence of benzene. First measurements of the absolute rate constants for hydrogen abstraction by the "free" chlorine atom and the chlorine atom-benzene .pi.-complex. Identification of these two species as the only hydrogen abstractors in these systems

Pulseradiolysis and laser flash photolysis techniques have been used to generate and kinetically characterize the chlorine atom-carbon disulfide molecular complex (Cl . /CS 2 ) in CCl 4 solution. The transient absorption spectrum of Cl . /CS 2 has been generated from three independent Cl . sources: pulseradiolysis of CCl 4 , 266-nm photodecomposition of CCl 4 , and photodissociation of Cl 2
