Abstract

original image

Der Einfluss des Lösungsmittels: Die nicht-adiabatische Inversionsdynamik der angeregten Zustände der Photosäure 1-Naphthol wurde mittels Femtosekundenspektroskopie verfolgt (siehe Bild; IC=interne Konversion). Die energetische Reihenfolge der angeregten Zustände La und Lb des 1-Naphthols kann in polarem Dimethylsulfoxid in 60 fs umgekehrt werden.
