Spectroscopy and Analytical Chemistry

Seeing the Unseen: Tools for Identifying Compounds

Spectroscopy uses light to probe molecules, revealing their structures and compositions. Analytical chemistry provides the framework for quantifying and identifying chemical substances—skills tested heavily on the GRE.

Main Techniques

  • UV-Vis Spectroscopy: Measures electronic transitions.
  • Infrared (IR) Spectroscopy: Detects molecular vibrations.
  • NMR Spectroscopy: Explores atomic environments, especially in organic chemistry.
  • Chromatography: Separates mixtures for analysis.

Real-World Use

These methods are essential in fields from environmental science (detecting pollutants) to medicine (drug purity testing).

Examples

  • Identifying aspirin using IR and NMR spectra.

  • Measuring water quality by detecting metal ions with atomic absorption spectroscopy.

In a Nutshell

Spectroscopy and analysis help chemists understand and identify substances.
