Abstract:

In this work a noise probe method to detect Raman bands in spectra has been developed. The effectiveness of this approach is demonstrated with the use of silica and gypsum Raman spectra obtained under variable experimental conditions. The advantage of the proposed method stems from the fact that the location of the Raman bands is automated by using software based upon a signal processing algorithm with the use of a personal computer. This approach avoids subjective errors. The method is shown to be suitable to locate Raman bands and so to be an efficient tool to identify materials on the basis of their characteristic Raman spectrum.
