Scientific definitions for spectroscopyspectroscopy [ spĕk-trŏs′kə-pē ] The analysis of spectra, especially light or mass spectra, to determine properties of their source.♦ In light or optical spectroscopy, the spectrum of a light source is analyzed through a spectroscope to determine atomic composition of a substance. In astronomy, phenomena such as red shift can also be analyzed.♦ In mass spectroscopy, a spectroscope is used to determine the composition of ions or charged molecules in a sample. Spectroscopy is also called spectrography. See also atomic spectrum spectroscope. The American Heritage® Science Dictionary Copyright © 2011.
