摘要: Abstract The dependence of the kinetic dynamics polystyrene dimer radical cation ( Ph 2 + ) on CCl4 concentration was investigated in a cyclohexane solution by nanosecond pulse radiolysis. A slow formation (k = 1.5 × 109 M−1 s−1) through electron transfer quenching excimer observed upon addition 10–100 mM CCl4. This led to an increase free ion yield (∼20%).
