Spectral line ratios information

The analysis of line intensity ratios is an important tool to obtain information about laboratory and space plasmas. In emission spectroscopy, the intensity...

of plasmas can often be inferred by taking ratios of the emission intensities of various atomic spectral lines. The presence of a magnetic field splits...

Spectral line shape or spectral line profile describes the form of an electromagnetic spectrum in the vicinity of a spectral line – a region of stronger...
