High resolution spectroscopy of neurotransmitter analogues: tryptamine and 5-methoxytryptamine — •Thi Bao Chau Vu, Marcel Böhm, and Michael Schmitt — Heinich-Heine-Universität Düsseldorf, Institut für Physikalische Chemie

The activity of biomolecules depends strongly on their structure. In case of different confomers of neurotransmitters line serotonine or melatonine the questions arises which is the most stable one in aqueous solution. We investigated the structure and conformational stabilization of microsolvated complexes of tryptamine and 5-methoxytryptamine, the builing blocks of the above neurotransmitters by rotationally resolved electronic spectroscopy. In the present talk the results of these experiments will be presented and compared to the results of ab initio calculations.
