A new sample for coherent multidimensional spectroscopy: Preparation of molecules on cold rare gas clusters — •Elena Leißler, Lukas Bruder, Ulrich Bangert, Marcel Binz, Friedemann Landmesser, Daniel Uhl, and Frank Stienkemeier — Institute of Physics, University of Freiburg, Hermann-Herder-Str. 3, 79104 Freiburg, Germany

The recent advances of coherent multidimensional spectroscopy towards the gas phase made new samples accessible, featuring low internal temperatures and minimal environmental perturbation [1]. In particular, matrix isolation on rare gas clusters is of interest, as it provides a high degree of control over molecule-molecule and molecule-solvent interactions. Doping the rare gas clusters with variable numbers of different molecules directly dictates the interaction strength. Here we present a cluster beam apparatus with a highly flexible doping unit. The unit features high dopant densities and the possibility to simultaneously dope with various molecules out of the gas and solid phase.
