Optics:

The first collecting mirror is in a specially designed dipole vacuum chamber. Point to point focusing optics transfer the IR light first through a thin diamond window that separates UHV from rough vacuum and then into the high resolution Bruker spectrometer.
 

Techniques:

• Horizontal Microscope for High Pressure Studies Using Diamond Anvil Cells
• Bruker IFS 125 HR, 9 compartments
  • Gas phase
    • Cells
      • 2 m cold multi-reflection (MR) cell
        (Path lengths up to 80 m, temperatures down to -80°C)
      • 0.3 m ambient MR cell
        (Path lengths up to 10 m)

Endstation(s):

• Bruker IFS 125 HR, 9 compartments

Far-IR Endstations and Capabilities:

• The Far-IR endstation centers around a Bruker IFS125HR Ultra-high spectral resolution (= 0.00096 cm-1)  Fourier transform spectrometer with a maximum optical path difference of 9.4 m.  The present set of optical components and detectors cover the spectral region between 10 and 12000 cm-1.
  • High resolution absorption spectroscopy of gas-phase molecules (10 - 4000 cm-1)
  • A 0.30 m room temperature multi-reflection cell yielding absorption paths ranging from 1.2 to 12 m to study stable gases that are weak absorbers or possess low-amplitude modes of vibration
  • A 2.00 m coolable (down to 200 K) multi-reflection cell for absorption paths ranging from 8 to 100 m to study stable gases that are also weak absorbers or possess low-amplitude modes of vibration
  • 1.5 meter Glow Discharge Cell (maximum path length 24m)
  • Horizontal Microscope for High Pressure Studies (10-5000 cm-1), the objectives of this microscope have a Numerical Aperture of 0.5 and have a working distance of 47 mm, allowing for space for Diamond Anvil High Pressure cells. (Please contact Brant Billinghurst for more details before requesting beamtime)
  • Attenuated total reflectance (ATR) is now available for the study of condensed phase samples.
