Detecting the Molecular Compound
With the method of infrared spectroscopy the resonant vibrations of different organic molecular compounds can be detected. In this way, particularly with elastomers, functional groups are detected and this allows a relatively certain polymer determination. Modern methods like the ATR-technique (attenuated total reflection) permit the performance of these tests even non-destructive.
Besides each formula has a characteristic band spectrum of extracts which makes the infrared spectroscopy to a popular method to prove the sampling condition of a formula with regard to the present substances.
