Sequential Intramolecular Relaxation of Vibrational Energy in a Homologous Series of 2-Alkyl Radicals

The nature of the dinamics of intramolecular energy transfer for a homologous series of 2-alkyl radicals vibrationally excited via a chemical activation technique has been probed.It is found that, for the excited species resulting from terminal hydrogen addition to 1-octene, 1-decene, and 1-dodecene, the specific rate constant for decomposition to propene is pressure dependent.This indicates the importance of sequential energy relaxation from the site of the initial double bond opening to the adjacent C atom before evantual energy randomization of the whole radical takes place.
