	Spectroscopy - Wikipedia, the free encyclopedia
		Spectroscopy is the study of spectra, that is, the dependence of physical quantities on frequency.
		Spectroscopy is often used in physical and analytical chemistry for the identification of substances, through the spectrum emitted or absorbed.
		Raman spectroscopy uses the inelastic scattering of light to analyse vibrational and rotational modes of molecules.

	Zoom Astronomy Glossary: Spectroscopy
		Spectroscopy is a technique in which the visible light that comes from objects (like stars and nebulae) is examined to determine the object's composition, temperature, motion, and density.
		Spectroscopy was discovered in 1859 by Gustav Robert Kirchhoff and Robert Wilhelm Bunsen (of Bunsen burner fame).
		Spectroscopy is a scientific technique in which the visible light coming from objects (like stars and nebulae) is examined to determine the object's composition, temperature, density, and velocity.

	General Spectroscopy Overview
		For example, in fluorescence emission spectroscopy, the frequency and amount of light scattered by the sample is measured as the frequency of the laser light is varied.
		One potential limitation to resolution in the spectroscopy of gases arises from the motion of the atoms or molecules relative to the observer.
		In spectroscopy, the principal interferometers are those developed by the American physicist A.A. Michelson (1881) in an attempt to find the luminiferous ether--a hypothetical medium thought at that time to pervade all space--and by two French physicists, Charles Fabry and Alfred Perot (1896), specifically for high-resolution spectroscopy.

	NMR Spectroscopy
		Nmr spectroscopy is therefore the energetically mildest probe used to examine the structure of molecules.
		Unlike infrared and uv-visible spectroscopy, where absorption peaks are uniquely located by a frequency or wavelength, the location of different nmr resonance signals is dependent on both the external magnetic field strength and the rf frequency.
		C nmr spectroscopy is the use of high-field pulse technology coupled with broad-band heteronuclear decoupling of all protons.

		Spectroscopy is defined as: "The study of spectra, including the position and intensity of emission and absorption lines."[F1] Scientists can study the light coming from distant stars to find information about those stars.
		Spectroscopy has also revealed the fact that the sun is composed mainly of hydrogen and helium.

	Amateur Spectroscopy
		Spectroscopy by definition is the decomposition of electromagnetic radiation (Visible light in this case) into the frequency domain.
		Each chemical element emits or absorbs radiation at defined frequencies hence the light source may then be analyzed for it's chemical makeup.With the advent of inexpensive CCD technology such as the Cookbook series of imagers and more recently webcams the amateur now has multiple options for the recording of astronomical spectra.
		The application is quite capable of calibrating both non-linear prism spectra as well as the mostly linear dispersion produced by a transmission or reflective type grating.

	Raman Spectroscopy
		In the discussion of Raman spectroscopy, we use language from particle theory and we say that a photon is scattered by the molecular system.
		Raman Spectroscopy is based on the Raman effect, which is the inelastic scattering of photons by molecules.
		For highly symmetric polyatomic molecules possessing a center of inversion (such as benzene) it is observed that bands that are active in the IR spectrum are not active in the Raman spectrum (and vice-versa).

		Spectroscopy is the study of light as a function of wavelength that has been emitted, reflected or scattered from a solid, liquid, or gas.
		Spectroscopy's historical disadvantage is that it is too sensitive to small changes in the chemistry and/or structure of a material.
		Spectroscopy is more sensitive to the presence of clays, iron oxides, iron hydroxides, quartz, and other minerals with strong absorption bands at levels significantly lower than other methods such as X-ray diffraction (e.g.

		Spectroscopy is the use of the absorption, emission, or scattering of electromagnetic radiation by matter to qualitatively or quantitatively study the matter or to study physical processes.

		A plot of the frequency of the incident radiation vs. some measure of the percent radiation absorbed by the sample is the absorption spectrum of the compound.
		Vibrational spectroscopy (or infrared spectroscopy) measures transitions from one molecular vibrational energy level to another, and requires radiation from the infrared portion of the electromagnetic spectrum.
		An IR spectrum is displayed as a plot of the energy of the infrared radiation (usually expressed in wavenumbers) versus the percent of light transmitted by the compound.

		Spectroscopy is the use of the absorption, emission, or scattering of electromagnetic radiation by atoms or molecules (or atomic or molecular ions) to qualitatively or quantitatively study the atoms or molecules, or to study physical processes.
		For atoms excited by a high-temperature energy source this light emission is commonly called atomic or optical emission (see atomic-emission spectroscopy), and for atoms excited with light it is called atomic fluorescence (see atomic-fluorescence spectroscopy).
		For molecules it is called fluorescence if the transition is between states of the same spin and phosphorescence if the transition occurs between states of different spin.
