Frequently Asked Questions
The study of the interaction between matter and electromagnetic radiation. Different spectroscopic techniques (UV-Vis, IR, NMR, mass spectrometry) provide information about molecular structure, composition, and concentration. Spectroscopy is fundamental to analytical and physical chemistry.
Spectroscopy is used to identify chemical compounds and determine their structures. UV-vis spectroscopy measures concentrations of coloured compounds. NMR spectroscopy is the primary tool for determining organic molecular structure in pharmaceutical research.
UV radiation used in some spectroscopic instruments can damage eyes and skin. Radiofrequency radiation from NMR is non-ionising but strong magnetic fields require safety precautions.
