Static and Time resolved Fourier Transfer Infrared Spectroscopy (FTIR)

This approach spectrally resolves large numbers of molecular vibrations to identify and study chemical bonds that make up biochemical systems such as proteins, lipids and small molecules, providing information on protonation states, bond strengths, molecular structure and environment.

  • Bruker IFS66-V6 vacuum bench FTIR equipped with rapid-scan (100 spectra per sec at 12 cm-1 resolution), step-scan (down to 10 nsec time resolution). KBr and quartz Beam Splitter couple with MCT, DTGS and Si detectors for mid IR to Vis measurements. Vacuum optics minimize interference from water vapor and CO2 absorptions. KBr widows to sample compartment allow use of Si and diamond ATR crystals for easy and rapid sample replacement down to 400 cm-1.  These can be combined with a spectro-electrochemical cell and fiber optics to perform oxidation and reductive reactions with simultaneous infrared and visible spectroscopy.  CaF2 windows with standard FTIR Harrick cells, including temperature control, permit spectra down to cm-1.  FT-Raman module with InGaAs detector probes FT-Raman transition down to ~50 cm-1 on either side of 1064 nm Raman excitation notch filter.
