    Description / Table of Contents: UV-Laserphotochemie: Abfang des Norrish-Typ-II-Triplett-Diradikals 1-Hydroxy-4-methyl-1-phenyl-1,4-pentandiyl mit molekularem SauerstoffDie Lebensdauer des Triplett-Diradikals 2 (3ι = 131 ± 5 ns), erzeugt durch Laserphotolyse (334 nm) von 4-Methyl-1-phenyl-1-pentanon (1) in Methanol, wurde durch Abfang mit molekularem Sauerstoff bestimmt. Diese Lebensdauer stimmt mit dem durch Laserblitzphotolyse erhaltenen Wert (3ι = 97 ns) gut überein und belegt damit die Verläßlichkeit der Sauerstoff-Abfangtechnik. Das Abfangprodukt wurde durch eine unabhängige Synthese dargestellt und als 3-Hydroxy-1,2-dioxolan 9 identifiziert, das Ringtautomer des Hydroperoxids 6.
    Notes: The triplet lifetime (3ι = 131 ± 5 ns) of diradical 2, produced in the laser photolysis (334 nm) of 4-methyl-1-phenyl-1-pentanone (1) in methanol, was determined by dioxygen trapping. This lifetime agrees well with the value determined by laser flash photolysis (3ι = 97 ns), thereby establishing the reliability of the trapping technique. The trapping product was prepared by independent synthesis and characterized as 3-hydroxy-1,2-dioxolane 9, the ring tautomer of hydroperoxide 6.
