    Description / Table of Contents: Bromine Superoxide: Generation and Photoisomerization into Bromine DioxideFlash pyrolysis of a gas mixture containing bromine, oxygen and argon yields bromine superoxide, which can be identified IR- and UV-spectroscopically after trapping the pyrolysate at 12 K. Matrix irradiation transfers bromine superoxide into bromine dioxide. The backreaction can be induced by changing the wavelength. Even at room temperature a detectable amount of bromine superoxide is formed upon preparing a mixture of gaseous bromine, oxygen and argon.
    Notes: Die Blitzpyrolyse eines Gasgemischs von Brom, Sauerstoff und Argon liefert Bromsuperoxid. Dieses kann nach Abschrecken des Pyrolysats auf 12 K IR- und UV-spektroskopisch identifiziert werden. Matrixphotolyse gestattet die Umwandlung von Bromsuperoxid in Bromdioxid. Letzteres kann durch geeignete Wahl der Wellenlänge wieder in Bromsuperoxid zurückverwandelt werden. Bereits bei Raumtemperatur bildet sich in einem Br2/O2/Ar-Gasgemisch eine nachweisbare Menge an Bromsuperoxid.
