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. The emission spectrum of an element or compound is how bright certain frequencies are when energy is added to the atoms or molecules.

This immediate feedback gives students a kinesthetic connection between making the emission graph and viewing the spectrum being represented. An emission spectrum is the type of light a particular substance emits every element has a unique emission spectrum, which is. Welcome welcome to the asu thermal emission spectroscopy laboratory spectral library this library consists of thermal infrared emission spectra (typically 2000 - 220 cm-1) of a variety of geologic materials. 086 - emission and absorption spectra in this video paul andersen explains how the photons emitted from or absorbed by an atom or nuclei is directly related.

The study of the interaction of light with matter is called spectroscopy spectroscopy had been a fundamental part in the development of chemical molecular theory, and it can be used for both qualitative and quantitative analysis of matter.
Because of their novel electronic configurations, fluorochromes have unique and characteristic spectra for absorption (usually similar to excitation) and emission. Other articles where emission spectrum is discussed:a pattern is called an emission, or bright-line, spectrum 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.
