Cryogenic Matrix Isolation FTIR Spectroscopy with Diamond Beam Splitter. — •Dmitry Strelnikov1, Bastian Kern2, Christoph Sürgers3, and Manfred Kappes11Physikalische Chemie, KIT, Karlsruhe, Germany — 2MPI for Solid State Research, Stuttgart, Germany — 3Physikalisches Institut, KIT, Karlsruhe, Germany

FTIR spectroscopy is a robust technique to obtain broad band spectra of various species. In case of valuable samples, which can be kept only at cryogenic temperatures and require long preparation time, one would like to measure in all accessible spectral regions. To extend the spectroscopic measurement range from Far-IR to near-IR a synthetic diamond beam splitter without compensator plate and UHV diamond viewports were installed in a Bruker IFS66v/S FTIR spectrometer. We have also modified the IR detector chamber to allow measurements with 5 different detectors. We demonstrate performance of the upgraded FTIR spectrometer by presenting measurements of matrix isolated fullerene ions and an adhesive tape.
