AN 97100 - The Use of FT-Raman Spectroscopy and Chemometric Procedures in the Analysis of Polymers


Infrared spectroscopy is one of the major analytical techniques in industrial polymer laboratories. Conventional Raman spectroscopy, although historically used extensively in research applications, has never become a routine technique in this field. This is mainly due to the appearance of strong fluorescence backgrounds upon excitation with visible (i.e. high frequency) lasers. These strong backgrounds often completely overwhelm the weak Raman spectrum.
