Spectrum analysis (Topical Term)

Spectrometry and spectroscopy: what's the difference?, 2020, via ATA Scientific website, viewed Aug. 10, 2020 (Spectroscopy is the study of the absorption and emission of light and other radiation by matter; Spectrometry is the measurement of the interactions between light and matter, and the reactions and measurements of radiation intensity and wavelength. In other words, spectrometry is a method of studying and measuring a specific spectrum, and it's widely used for the spectroscopic analysis of sample materials)

A dictionary of chemistry, 2020 (spectrometer: Any of various instruments for producing a spectrum and measuring the wavelengths, energies, etc., involved. A simple type, for visible radiation, is a spectroscope equipped with a calibrated scale allowing wavelengths to be read off or calculated. ... Instruments for obtaining spectra of particle beams are also called spectrometers; spectroscopy: The study of methods of producing and analysing spectra using spectroscopes, spectrometers, spectrographs, and spectrophotometers)

Dictionary.com, Aug. 10, 2020 (spectrometry: The observation and measurement of wavelengths of light or other electromagnetic radiation; spectroscopy: the science that deals with the use of the spectroscope and with spectrum analysis.)
