- the science that deals with the use of the spectroscope and with spectrum analysis.
Origin of spectroscopy
Examples from the Web for spectroscopy
In the early days of spectroscopy many doubters said, What good is all this?Inventors at Work
Celestial photography, photometry and spectroscopy sum up its fields of activity.
Simple as it is in its broad outlines, spectroscopy is, in reality, one of the most intricate branches of modern science.The Outline of Science, Vol. 1 (of 4)
J. Arthur Thomson
His most important work was concerned with the conduction of heat and with spectroscopy.
In spectroscopy, Blopolsky has sought to determine the period of rotation of Venus on her axis.Astronomy
- the science and practice of using spectrometers and spectroscopes and of analysing spectra, the methods employed depending on the radiation being examined. The techniques are widely used in chemical analysis and in studies of the properties of atoms, molecules, ions, etc
- The study of spectra, especially experimental observation of optical spectra.
- 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 branch of science devoted to discovering the chemical composition of materials by looking at the light (and other kinds of electromagnetic radiation) they emit. Scientists use spectroscopy to determine the nature of distant stars and galaxies as well as to identify and monitor the production of products in factories.
