Electromagnetic spectroscopy

Article

Electromagnetic spectroscopy studies the interaction of electromagnetic radiation with matter across regions ranging from radio waves to gamma rays. Different frequencies probe different forms of physical structure and energy transitions.

Radio and microwave spectroscopy can examine rotations, spins, and magnetic environments. Infrared spectroscopy commonly measures molecular vibrations, while visible and ultraviolet spectroscopy often probes electronic transitions.

X-ray and gamma-ray methods investigate inner electrons, nuclei, high-energy processes, and material composition. Spectra may be produced by absorption, emission, scattering, fluorescence, or resonance.

These methods are used to identify substances and determine composition, structure, temperature, motion, fields, and reaction conditions in chemistry, physics, astronomy, biology, medicine, and materials science.
