A STANDARDIZED INTENSITY SCALE FOR FOURIER-TRANSFORM RAMAN-SPECTRA OF LIQUIDS

A method is proposed for producing a standardised intensity scale for liquid spectra measured on Fourier transform Raman spectrometers. The method uses hexachlorobutadiene as an external standard, and relies upon the high degree of reproducibility available between spectra on a Fourier transform Raman instrument. This procedure is designed primarily to be simple to use and easy to automate in order that it may be applied in routine analytical laboratories with a minimum of recording and processing time. Limitations to the technique and alternative means of standardisation are discussed.
