Spectroscopy is a term used to describe measurements involving electromagnetic radiation, such as infrared spectroscopy, ultraviolet spectroscopy, etc. The operation of each type of instrument depends on the form of spectrometry used in the instrument. 0. Strictly speaking, a spectrometer is any instrument used to view and analyze a range (or a spectrum) of a given characteristic for a substance (for example, a range of mass-to-charge values as in mass spectrometry), or a range of wavelengths as in absorption spectrometry like nuclear magnetic radiation spectroscopy or infrared spectroscopy). Spectroscopy vs spectrometry Spectroscopy Latin specere “to look at” Greek skopia “to see”-metry Greek metria “process of measuring” Spectroscopy traditionally involves the absorption of some type of energy leading to an “excited state” that is subsequently emitted - This returns the molecule to the initial state non-destructively. Spectrophotometry is a tool that hinges on the quantitative analysis of molecules depending on how much light is absorbed by colored compounds. It is more specific than the general term electromagnetic spectroscopy in that spectrophotometry deals with visible light, near-ultraviolet, and near-infrared, but does not cover time-resolved spectroscopic techniques. Ultimately, a spectrophotometer is able to determine, depending on the control or calibration, what substances are present in a target and exactly how much through calculations of observed wavelengths. Important features of spectrophotometers are spectral bandwidth and linear range of absorption measurement. In astronomy, the term spectrophotometry refers to the measurement of the spectrum of a celestial object in which the flux scale of the spectrum is calibrated as a function of wavelength, usually by comparison with an observation of a spectrophotometric standard star, and corrected for the absorption of light by the Earth's atmosphere. Essentially, spectroscopy is the study of radiated energy and matter to determine their interaction, and it does not create results on its own.
