 Title: THE NEAR-IR HIGH RESOLUTION SPECTRUM OF JET-COOLED ETHYL PEROXY RADICALS Creators: Dupré, Patrick; Rupper, Patrick; Miller, Terry A. Issue Date: 2007 Publisher: Ohio State University Abstract: The jet-cooled high resolution CRDS spectra of the ethyl peroxy radicals, ${\rm C}_{2}{\rm H}_{5}{\rm OO}$ and ${\rm C}_{2}{\rm D}_{5}{\rm OO}$ have been recently obtained for the $\tilde{A}\,^{2}A^{'}\leftarrow\tilde{X}\,^{2}A^{''}$ $0_{0}^{0}$ band. The observation of this weak transition: signal of a few ppm/pass for the most populated $G$ conformer has been possible by using a narrow linewidth (Fourier-transform-limited) laser source% } and a hydrogen Raman shifter (resolution: $250-300\,{\rm MHz}$). The radicals are produced by creating a plasma (by using a DC or a RF discharge) inside a pulsed slit nozzle% }. We will discuss the analysis of these complex spectra.
