Near-IR cavity ringdown spectroscopy and kinetics of the isomers and conformers of the butyl peroxy radical.
Cavity ringdown spectra of butyl peroxy radicals have been obtained for their A-X electronic transition in the near-IR. The radicals were produced by two independent chemical methods, allowing unambiguous assignment of the spectra of the four butyl peroxy isomers with probable conformer assignments also possible for a number of cases. Using the analyzed spectra semiquantatively, isomer specific rate constants for butyl peroxy self-reaction were measured, as was the relative reactivity of the various sorts of H atoms in butane to Cl atom attack.
