Observation of the Ã−X Electronic Transition of the 1-C₃H₇O₂ and 2-C₃H₇O₂ Radicals Using Cavity Ringdown Spectroscopy

Abstract

Cavity ringdown spectra of the A-X electronic transition of the 1-propyl and 2-propyl peroxy radicals are reported. Spectroscopic assignments are facilitated by implementing several production mechanisms, either isomer-specific or not. Assignments of specific spectral lines to particular conformers of a given isomer are suggested. Observations on the temporal decay of the various species are reported.
