Abstract

Band-target entropy minimization (BTEM) was applied for the extn. of pure component Raman spectra from samples exhibiting a significant thermal background due to sample emission. In this method, singular value decompn. was first used to calc. the right singular vectors of the spectroscopic data matrix. Then the non-noise right singular vectors were examd. for localized spectral features, which were subsequently used for spectral recovery. These local features were targeted with the BTEM algorithm to recover the pure component Raman spectra. Accordingly, the interfering thermal background was removed. This method of anal. is applied to graphite and barium sulfate Raman spectroscopic data. [on SciFinder (R)]
