## Abstract **Nicht verboten**: Thermische 4__n__‐Elektronen‐Elektrocyclisierungen von Hückel‐Strukturen verlaufen über „erlaubte“ konrotatorische Pfade. Bei einer Möbius‐Topologie können dagegen die Woodward‐Hoffmann‐Regeln außer Kraft treten, sodass ein „verbotener“ disrotatorischer Pfad bevorzug

## Abstract **Not forbidden**: Thermal 4__n__ electron electrocyclic reactions of Hückel topology structures proceed via “allowed” conrotatory pathways. However, for a Möbius topology, the Woodward–Hoffmann rules may be reversed and a “forbidden” disrotatory pathway can be preferred as shown theore
A time-resolved ENDOR spectrum of the triplet state of the primary donor of photosystem II in isolated reaction centers has been obtained at cryogenic temperatures. Selective excitation of donor molecules, which have their z triplet axes parallel to the magnetic field, has permitted the measurement
