Ultrafast photophysical processes in electronically excited flavin and beta-carotene

Quick, Martin 08 June 2016 (has links)
Die Kombination aus Breit-Band Spektroskopie-Methoden ermöglicht eine umfassende Einsicht in das elektronische System von Molekülen im angeregten Zustand. Am Beispiel des Riboflavin in saurer Umgebung wird der Protonen-Transfer aus der Lösung auf den Chromophor mittels transienter Absorption und -Fluoreszenz im S1-Zustand beobachtet. Mittels transienter Absorption- und Femtosekunden-stimulierter Raman-Spektroskopie wird der Populationstransfer in den elektronischen Grundzustand im beta-Karotin verfolgt und charakterisiert werden. / The combination of broadband spectroscopic methods allows a comprehensive view of the electronic system of molecules in the excited state. On riboflavin in acidic environment the proton-transfer is observed with transient absorption and -flurescence in the S1-state. With transient absorption and femtosecond-stimulated Raman-spectroscopy the population transfer into the electronic ground-state is followed and characterized.
