(uncountable) The scientific study of spectra. / (analytical chemistry, countable) The use of spectrometers in chemical analysis.

plural of spectroscopy

(analytical chemistry) An analytical technique that exploits fine differences in the frequency of nuclear magnetic resonance in protons (and ¹³C atoms, etc.) within organic compounds that depends on their neighbouring atoms.

(analytical chemistry) The spectroscopic study of the interaction of matter with infrared radiation; used as an analytical tool to identify (mostly organic) compounds.

(physics) The study of the interaction of matter with electromagnetic radiation in the microwave region of the spectrum.

(analytical chemistry) A form of spectroscopy that uses the Raman effect to study low-frequency vibrational and rotational modes of molecules.

(physics, chemistry) An analytical technique that analyzes the fluorescence produced by a sample; fluorometry or spectrofluorimetry.

(physics) The analysis of the energy level structure of a quantum system through its response to driving-field amplitude rather than frequency

A form of spectroscopy that analysis absorption spectrums.
