Abstract

A series of peroxyl radical clocks has been developed and calibrated based on the competition between the unimolecular β-fragmentation (k β) of a peroxyl radical and its bimolecular reaction with a hydrogen atom donor (k H). These clocks are based on either methyl linoleate or allylbenzene and were calibrated directly with α-tocopherol or methyl linoleate, which have well-established rate constants for reaction with peroxyl radicals (k ...
