study of spectra, especially experimental observation of optical spectra. It has been the basis of modern quantum physics, and provides an understanding of the interaction between electromagnetic radiation and matter.
the study of optical spectra (wavelengths)
The science of analyzing the spectra of stars or other sources of light.
the dispersion of light (i.e. from a star) into the component colours.
Study of the molecular absorption of light. Different wavelengths and types of light can tell different things about the molecules' identity and condition. Proteins are often studied using fluorescence and infrared spectroscopy. Fluorescence spectroscopy induces molecules to emit light by the application of laser energy. Fourier-transform infrared (FTIR) spectroscopy uses a mathematical logarithm to interpret the vibrations of functional molecular groups and highly polar bonds. It can produce a biochemical "fingerprint" illustrating the vibrational features of all sample components, and it can be used to learn about protein structure.
The science and study of the spectrum.
the study of spectral lines from different atoms and molecules. Spectroscopy is an important part of studying the chemistry that goes on in interstellar clouds. (See also text in HighSpec.)

that branch of physics and astronomy dealing with the color or wavelength composition of composite or white light.
the analysis of an object from its spectrum.
An analytical technique devoted to the identification of the elements and the elucidation of atomic and molecular structure by measurement of the radiant energy absorbed or emitted by a substance in any of the wavelengths of the electromagnetic spectrum in response to excitation by an external energy source.
The study of spectral lines from different atoms and molecules. Spectroscopy is an important part of studying the chemistry that goes on in stars and in interstellar clouds.

the study of sky or heavens using a spectrometer.
is the study of light coming from an object by examining the intensity at different wavelengths - and a very powerful tool for investigating the composition of surfaces and atmospheres.
The branch of science that deals with deducing as much as possible about the workings of the Universe, by studying the light emitted or otherwise modified by the objects that inhabit it.
The study of spectral lines (light given off at a specific frequency by an atom or molecule) from different atoms or molecules that can indicate the chemical composition of stars, gas, or dust.
The study of the electromagnetic radiation frequencies absorbed by matter.
The study of light from stars or planets. A spectrum of light is produced by magnifying light from objects with a telescope, and separating it into colours with a prism or diffraction grating. The spectrum can reveal the chemical composition of the star, or constituents of a planet's atmosphere. More.
The physics that deals with the theory and interpretation of electromagnetic radiation.
Study of a radiation spectrum (emitted, absorbed or diffused).
The science that deals with the use of the spectroscope and with spectrum analysis.A spectroscope is an optical device for producing and observing a spectrum of light or radiation from any source.
A field of Analytical Science in which various energies of light (electromagnetic radiation) are used to study materials.
The study of the way in which atoms absorb and emit light electromagnetic radiation. Spectroscopy allows astronomers to determine the chemical composition of stars.
The study of the production, measurement and interpretation of electromagnetic spectra.
The study of molecular or atomic structure of a substance by observation of its interaction with electromagnetic radiation.
The study of absorption and emission of gases.
the study of spectra from astronomical objects
the study of spectra, including the position and intensity of emission and absorption lines.
The science that deals with the use of the spectroscope and with spectrum analysis in which the intensity of light as a function of wavelength is examined.
spectrometry; spectroscopic. Spectroscopy is analysis of the interaction between electromagnetic radiation and matter. Different types of radiation interact in characteristic ways with different samples of matter; the interaction is often unique and serves as a diagnostic "fingerprint" for the presence of a particular material in a sample. Spectroscopy is also a sensitive quantitative technique that can determine trace concentrations of substances.
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.
The use of the absorption, emission and scattering electromagnetic radiation by atoms or molecules (or atomic and molecular ions) to qualitatively and quantitatively study substances or its physical properties. Tetraselmis sp.- green algae used in the experiment.
study of spectra, especially optical spectra, which are graphs depicting the continuum of wavelengths of light
The study of the distribution of a characteristic of a system or phenomenon, especially the distribution of energy emitted by a system or the distribution of atomic or subatomic particles in a system.
The study of the electromagnetic spectrum.
The analysis of light by separating it by wavelengths (colors, in visible light).
An observational and analysis technique designed to disperse radiation into itS component wavelengths in order to study in fine detail the way that matter emits or absorbs radiation.
A technique used in chemical analyses which is based on the principle that many substances, when crossed by a beam of light, allow a unique and well-defined fraction of that light to pass or emit a well-defined fraction of radiation when returning from an atomic vapor state to their fundamental state.
The production and study of spectra.
The study of the interaction between matter and radiation. Since the energy levels in all atoms and molecules are discrete (quantized), the absorption or emission of radiation occurs at distinct energies ( frequencies) characteristic of a given chemical. The energy levels probed may be rotational ( microwave region), vibrational ( infrared region), or electronic (visible or ultraviolet). In mass spectroscopy, molecules are ionized and the different masses selected by use of an electric or magnetic field. Many spectroscopic techniques have been used to identify molecules or atoms in the atmosphere.
The study and interpretation of a celestial object's electromagnetic spectrum. A spectrograph or spectrometer is used to analyze an object's electromagnetic spectrum.
Spectroscopy is the study of matter and its properties by investigating light, sound, or particles that are emitted, absorbed or scattered by the matter under investigation.
