Far-Infrared Spectroscopy of Molecules and Aggregates in Helium Nanodroplets at FELIX — •Gerhard Schwaab1, Raffael Schwan1, Devendra Mani1, Nitish Pal1, Britta Redlich2, Lex van der Meer2, and Martina Havenith1 — 1Physikalische Chemie 2, Ruhr-Universität Bochum — 2FELIX Laboratory, Radboud University Nijmegen
Helium nanodroplets provide the opportunity to study molecules and molecular aggregates at temperatures of 0.37 K in a suprafluid matrix. Recently we have moved one of our helium droplet machines to the free electron laser facility FELIX in Nijmegen. First test molecules included SF6, water, water clusters and water-HCl clusters.
The high output energy and broad frequency coverage of the FELIX I and FELIX II beamlines allows access to the low frequency (ν>100cm−1) far-infrared range in spite of the low energy per photon. Esecially the spectrum of small water clusters in this region is astonishingly rich. An overview of the experimental setup and the results of our latest micro-solvation studies will be given.
