Impulsive model of photodissociation

Witryna15 kwi 2010 · Abstract This study photolytically generates, from 2-bromoethanol photodissociation, the 2-hydroxyethyl radical intermediate of the OH + ethene reaction and measures the velocity distribution of the stable radicals. We introduce an impulsive model to characterize the partitioning of internal energy in the C (2)H (4)OH fragment.
