It is found that,in a first-order differential Raman spectrum,almost all noise peaks are confined within a narrow horizontal band-like region with the base line going through its middle,whereas thesignal peaks shoot up and down much far beyond the region.Based onthis property,a new peak searching method with the aid of first-order differentiation is suggested.In this paper,a R_spectrumpeak labelling program for SPEX 1403 laser spectrometer with DMIBcomputer is reported.The result of peak labelling sho...
