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

plural of spectroscopy

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

(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.

(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.
