Abstract

en

The methylperoxy radical has been isolated in matrices of Ar + 10% O2 and its IR spectrum observed. The following isotopic species were used in the investigation: CH3, 13CH3, CD3, 16O2, 18O2, and 16O18O. A total of 64 frequencies were identified for the various isotopically labelled peroxy radicals. A normal coordinate analysis for the methylperoxy radical has been made. Good agreement between the observed and calculated frequencies was obtained.

Alkylperoxy- und Alkyl-Radikale. 2. Ultrarot-Spektrum und Normalkoordinaten-Analyse von CH3O2 und einigen isotopen Molekülen

Das Methylperoxy-Radikal wurde in einer Matrix (Ar + 10% O2) isoliert und das IR-Spektrum aufgenommen. Die folgenden isotopen Moleküle wurden eingesetzt und untersucht: CH3, 13CH3, CD3, 16O2, 18O2 und 16O18O. Im Gesamten wurden 64 Frequenzen den verschiedenen isotopen Peroxy-Radikalen zugeordnet. Es wurde eine Normalkoordinaten-Analyse des Methylperoxy-Radikals durchgeführt, die eine gute Übereinstimmung zwischen beobachteten und berechneten Frequenzen ergab.
