  1. Singulett-Sauerstoff By Benjamin Robotham, David Straub, Stefan Müller

  2. Sauerstoff • Chalkogen Bildet 2-atomige Moleküle (O2) Atmosphärischer Sauerstoff unter Normbedingungen reaktionsträge • Chemisch / photochemisch in eine aggressivere, stärker oxidierende Form umwandelbar

  3. Der „gewöhnliche“ Sauerstoff • O-Elektronen- konfiguration: • 1s²2s²p4 • Triplett-Sauerstoff 3O2

  4. Der angeregte Sauerstoff • Singulett-Sauerstoff 1O2 • Zwei verschiedene Formen • ³O2 paramagnetisch • 1O2 diamagnetisch • Gesamtspin * 2 + 1

  5. Übergang von 1O2 zu 3O2 unter Emission von Licht rotes Leuchten

  6. Darstellung von 1O2 • Photochemisch: Minimale Lichtabsorption von 3O2 • Chemisch: Umsetzung von Hypochlorit mit Wasserstoffperoxid

  7. Chemische Darstellung Cl2 + 3 H2O  ClOH + HCl + 2 H2O  ClO- + Cl- + 2 H3O+ ClO- +HOOH  ClOOH + OH- ClOOH  HCl + 1O2

  8. Warum entsteht Singulett-Sauerstoff? Cl+OO2-H+
