What is Spectroscopy?

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.

Formula & Notation

λ_max ∝ 1/ΔE; Beer-Lambert: A = εlc

Other Names / Synonyms: Spectral analysis, spectrometry, spectrographic analysis

Properties & Characteristics

Spectroscopy is the study of the interaction between matter and electromagnetic radiation as a function of wavelength. Different types include UV-visible, infrared, NMR, and mass spectroscopy. Spectroscopic techniques exploit the absorption, emission, or scattering of radiation to obtain information about molecular structure. The Beer-Lambert law relates absorbance to concentration.

Uses & Applications

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.

Safety Information

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.

Always consult the SDS/MSDS before handling any chemical. This information is for educational purposes only.
