FOURIER-TRANSFORM RAMAN-SPECTROSCOPY USING A BENCH-TOP FT-IR SPECTROMETER

Fourier transform Raman spectroscopy has been performed with an inexpensive bench-top FT-IR spectrometer optimized for the near-infrared. The laser excitation source was from a continuous-wave Nd:YAG laser with an output at 1. 064 mu m. Spectra from solid samples, ground as powders, have been obtained. Many of these are well known to fluoresce in the visible region and are thus intrinsically difficult to study by the Raman method. The FT-Raman method is described, and improvements in the technique are considered.
