Experimental setup for stereoselective and enantioselective cluster catalysis — •Kathrin Lange, Bradley Visser, Martin Tschurl, Ulrich Boesl, and Ulrich Heiz — Lichtenbergstr.4, 85748 Garching

This work describes the design and construction of a vacuum system to produce, characterise and perform reactions with chiral gas phase metal clusters. It is believed that any produced population of chiral metal clusters will be a racemic mixture of both enantiomers. Thus a method to enable the identification of enantiomers must be implemented. In the current experiment this will be attempted through the introduction of a gas phase enantiopure chiral molecule into the cluster source from a second pulsed nozzle. The added molecule will bind to the metal cluster enantiomers with varying degrees of strength and thus may be probed by either vibrational (REMPI) or dissociation spectroscopy.
