emission spectrum definition

This energy is then given out as light of several definite wavelengths (colours). A spectral line is a dark or bright line in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Emission spectra bearing peaks with half-widths of less than 0.6 nm have been recorded for chrysene, pyrene, benzo[a]pyrene, and benz[a]anthracene, for example, in a cyclohexane-n-octane solvent mixture. The figure below shows the atomic emission spectrum of hydrogen. When light passes through a gas or cloud at a lower temperature than the light source, the gas absorbs at its identifying wavelengths, and a dark-line, or absorption, spectrum will be formed. Log in or create an account to start the emission spectrum entry. emission definition in English dictionary, emission meaning, synonyms, see also 'emission nebula',emission spectrum',back emission',field emission'. Therefore, spectroscopy can be used to identify the elements in matter of unknown composition. The interaction of radiation and matter is the subject of the science called spectroscopy. Emission Spectrum (definition) the spectrum of bright lines that is provided by a specific emitting substance as it loses energy and returns to its ground state OR the collection of frequencies of light given off by an "excited" electron jumping down to its ground state and emitting energy in the form of a photon. ‘First, the emission spectrum of the donor molecule must overlap with the absorbance spectrum of the acceptor.’ ‘In liposomes the excitation spectrum is shifted to higher wavelengths and the emission spectrum to lower wavelengths, typical of a fluorophore moving into a more hydrophobic environment.’ The spectrum of hydrogen is particularly important in astronomy because most of the Universe is made of hydrogen. Enrich your vocabulary with the English Definition dictionary The main difference between emission and absorption spectra is that an emission spectrum has different coloured lines in the spectrum, whereas an absorption spectrum has dark-coloured lines in the spectrum. BSL Physics Glossary - line emission spectrum - definition. Emission Spectrum. Define emission spectrum.
