RAMAN SPECTROSCOPY

 

Horiba Jobin Yvon  T64000 Raman spectrometer equipped with a BXFM Olympus 9/128 microscope and a Horiba JY Symphony CCD detector
Three lasers: 785 nm, 488 and 244 nm (Lexell SHG laser).

Raman spectra are acquired by irradiating samples with a powerful monochromatic laser. During irradiation the spectrum of the scattered radiation is measured at zero angle with a spectrometer. Intensities of the Raman lines (Stokes and anti-Stokes) are very weak and require very sensitive detectors (CCD). Raman spectroscopy can be considered as a complementary technique to FTIR spectroscopy and is related with structural features such as polarization. Macro samples (liquids and solids), ultra thin films and micro samples can be analyzed.

Typical applications

  • Study of thin layers of refractory elemental oxides
  • Use of Raman spectroscopy to study metal complexes
  • Identification of pigments
  • Analysis of micro samples using Raman microscopy
  • Study of the curing of phenolic resins
