Observation of the electronic transition of C6–C10 peroxy radicals

The A ∼ – X ∼ electronic transitions of C6–C10 peroxy radicals were observed in the near infra red. Spectra have been obtained for straight chain peroxy radicals: hexyl, heptyl, octyl, nonyl, and decyl including one C8 isomer, iso-octyl peroxy. The peroxy radicals were generated using hydrogen abstraction of the corresponding hydrocarbon precursors. Spectra was assigned through spectral/structural relationships established through prior studies of smaller peroxy radicals. The secondary peroxy isomer was determined to be the dominate carrier for the observed n-alkyl spectra. However, the iso-octyl peroxy radical was found to contain the tertiary and primary isomers in its spectrum.
