Comparison of FT near-IR Raman spectroscopy with FTIR photoacoustic and reflection measurements of solids
Abstract
We have compared methods for obtaining spectra of solids without any sample preparation, using a variety of commercial polymers in different physical forms. Raman spectra free of fluorescence were generated by using NIR excitation. IR spectra were obtained by measuring external reflection and with photoacoustic detection.
