(spÄk-trÅs'kÉ-pÄ) The analysis of spectra, especially light or mass spectra, to determine properties of their source. â 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.
