spectroscopy
/spɛkˈtrɒskəpi
/noun [mass noun]
The branch of science concerned with the investigation and measurement of spectra produced when matter interacts with or emits electromagnetic radiation.By that time atomism had been extended from chemistry and the kinetic theory to offer explanations in stereochemistry, electro-chemistry, spectroscopy and so on....
- To measure the efficacy of sunscreens, researchers used electron spin resonance spectroscopy to measure free radical production induced by UVA in the skin of white people.
- 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.
