INTENSIFICATION OF SPONTANEOUS RAMAN SPECTRA BY USE OF LIQUID CORE OPTICAL FIBERS

A new laser-Raman technique has been developed which employs low loss liquid core optical fibers and which yields intensity enhancements of similar 10**2 to 10**3 compared to conventional sample methods. The new fiber optics laser-Raman method should be of use in routine analytical procedures involving a wide range of solutions, for example, in the analysis of mixtures of hydrocarbons, of solutions of biologically interesting materials, of solutions of gases and solids, and in trace analyses involving pollutants.
