About the Laboratory

Vibrational spectroscopies are techniques that measure bond vibrations and allow researchers to identify various functional groups and molecular bonds within their samples. The two techniques available in the SSSC are Raman and Fourier Transform Infrared (FTIR) spectrocopies which detect changes in a chemical bond’s polarizability (ie. electron cloud around bond) and dipole moment, respectively. Both techniques are very complimentary, and can be used in many multi-disciplinary applications including:
  • Materials characterization
  • Catalysis characterization
  • Biological samples (protein secondary structure) and tissues
  • Geological samples - mineral identification
  • Plant materials and biomass samples
  • In situ monitoring

Raman and FTIR

Raman and Fourier Transform Infrared (FTIR) are vibrational spectroscopies that detect changes in a chemical bond’s polarisability (ie. The electron cloud around bond) and dipole moment, respectively. Both techniques are complimentary, and many vibrational modes are both Raman and IR active. In some cases, when there is a center of inversion in the crystal symmetry of the material, some vibrational bands will be only Raman active or IR active (not both – rule of mutual exclusivity). The Renishaw Invia Reflex Raman microscope (Renishaw, Gloucestershire, UK) located within the SSSC is its only kind in Canada, as it also equipped with an IlluminatIR II FTIR microscope accessory (Smith’s Detection, Danbury, CT). In addition, the Invia Reflex microscope supports multiple laser wavelengths, along with sophisticated software that allows automatic switching of lasers. This allows multiple excitation wavelength Raman and FTIR spectroscopies to be obtained on the same spot with relative ease for the general user!
