Spectroscopy \Spec*tros"co*py\, n. the art and science dealing with the use of a spectroscope, and the production and analysis of spectra; the action of using a spectroscope.


n. 1 (context uncountable English) The scientific study of spectrum. 2 (context analytical chemistry countable English) The use of spectrometers in chemical analysis.


n. the use of spectroscopes to analyze spectra [syn: spectrometry, spectroscopic analysis, spectrum analysis, spectrographic analysis]


Spectroscopy is the study of the interaction between matter and electromagnetic radiation. Historically, spectroscopy originated through the study of visible light dispersed according to its wavelength, by a prism. Later the concept was expanded greatly to include any interaction with radiative energy as a function of its wavelength or frequency. Spectroscopic data is often represented by an emission spectrum, a plot of the response of interest as a function of wavelength or frequency.

Spectroscopy (magazine)

Spectroscopy is a trade magazine published since 1985 by the Advanstar Publishers. Spectroscopy has an editorial goal to promote and support the use of spectroscopic instrumentation in applied research, environmental testing, quality control, and the life sciences.

''Spectroscopy ''covers many techniques from analytical chemistry to include: atomic absorption and emission (including plasma-based methods such as ICP and ICP-MS); ultraviolet spectroscopy, visible spectroscopy; infrared spectroscopy (including FT-IR and Near-infrared spectroscopy; fluorescence, phosphorescence, and luminescence; Raman spectroscopy and FT-Raman; X-ray (XRF, XRD, and microanalysis); mass spectrometry; magnetic resonance ( NMR, EPR, MRI); surface analysis ( ESCA, SIMS, Auger); and laser-based spectroscopic techniques.

Usage examples of "spectroscopy".

Rapid rotation can be detected astronomically by spectroscopy, letting light from a distant object pass consecutively through a telescope, a narrow slit and a glass prism or other device which spreads white light out into a rainbow of colors.

Thermographic investigation, infrared spectroscopy, radiography, electronic miscroscopy, and chemical analysis--all these scientific means have been used to prove or disprove that the image on the length of linen discovered in 1356 is that of Christ.

Performing astrometric measurements of nearby stars, extrasolar planet detection, extrasolar planet imaging, and atmospheric spectroscopy.

Spectroscopy revealed that the surface water was full of intriguing molecular debris, but guessing the relationship of any of it to the living carpets was like trying to reconstruct flesher biochemistry by studying their ashes.

He turned to the toxicology section, which had graphs of the results of the gas chromatography-mass spectroscopy of blood, cerebrospinal fiuid, and urine.

Although he did not utilize the spectral analyses to study the chemical composition of space, von Fraunhofer may nevertheless be considered to be the founder of astronomical optical spectroscopy.

It also included the toxicology section with the gas chromatography and mass spectroscopy graphs.

Astronomical spectroscopy is able to determine the chemical composition of collections of stars billions of light-years away.

We can detect by spectroscopy the same chemical elements, the same common molecules on other planets, stars and galaxies.

Sulfuric acid has an absorption feature, determined by infrared spectroscopy, at a wavelength of 11.

The next day Nemoto said she would take him to the surface, to see her infrared spectroscopy results at first hand.

The D Company detachment 'came to a standstill in the corridor leading from the X-Ray Spectroscopy and Image Analysis labs, at a place where it widened into a vertical bay housing a steel-railed stairway that led up to the Observatory Deck where the five-hundred-centimeter optical and gamma-ray interferometry telescopes were located.
