Info
On the basis of their spectroscopic properties,
molecules can be identified in a similar
manner to a fingerprint.
If unknown compounds such as undesirable
impurities occur, the molecular structure
is often determined by means of detective
work using spectroscopy.
In addition, the purity and the course of
entire chemical reactions can be followed.
