[mass noun]
The branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits electromagnetic radiation.
Example sentences

  • In comparison to gas chromatography and mass spectroscopy, the use of an electronic nose for detection of lung cancer offers several potential advantages, including ease of administration of the test and portability.



Pronunciation: /spɛktrəˈskɒpɪk/
Example sentences
  • The development of astrophysics spurred observatory growth as well as the spectroscopic analysis of starlight enabled astronomers to study not just the position of celestial bodies, but their composition as well.
  • MRI is based on the principle of nuclear magnetic resonance, a spectroscopic technique used by scientists to obtain microscopic chemical and physical information about molecules.
  • However, UK scientists will be involved in spectroscopic analysis from two hours after the impact when the telescopes in Australia come online.


Example sentences
  • They analyzed the remaining liquid spectroscopically and found three new sets of spectral lines.
  • Chloride binding by the proteins was assayed spectroscopically by monitoring the chloride-induced blue-shift of their absorbance spectra.
  • Total phosphorus was determined spectroscopically, using persulfate-oxidized samples, by molybdate blue absorption.


Example sentences
