Line Spectrum Definition & Meaning YourDictionary

A spectral line is a weaker or stronger region in an otherwise uniform and continuous spectrum, resulting from emission or absorption of light in a narrow frequency range, compared with the nearby frequencies. Spectral lines are often used to identify atoms and molecules. These "fingerprints" can be … See more Spectral lines are the result of interaction between a quantum system (usually atoms, but sometimes molecules or atomic nuclei) and a single photon. When a photon has about the right amount of energy (which is connected to its … See more Strong spectral lines in the visible part of the spectrum often have a unique Fraunhofer line designation, such as K for a line at 393.366 nm emerging from singly-ionized Ca , though some of the Fraunhofer "lines" are blends of multiple lines from several different See more • Absorption spectrum • Atomic spectral line • Bohr model See more There are a number of effects which control spectral line shape. A spectral line extends over a range of frequencies, not a single frequency (i.e., it has a nonzero linewidth). In … See more Bands The phrase "spectral lines", when not qualified, usually refers to lines having wavelengths in the See more • Griem, Hans R. (1997). Principles of Plasma Spectroscopy.
