Infrared and Raman spectroscopy are the most important methods of vibration spectroscopy. These methods are used for the chemical identification and characterization of different substances and have become established as important methods in material science as well as quality and process control. In particular, the chemical composition of materials has a decisive influence on their material properties, and the above-mentioned examination methods can make corresponding statements.

The spectroscopic methods are used for:

• the identification and structure elucidation of materials
• the determination of the composition of materials with respect to water, additive, filler content
• the identification of thermally induced degradation steps
• the characterization of processing parameters, in particular the thermal curing
• the surface analysis
• the destructive analysis of joints.
