Reference emission lines

Emission lines are referenced using the line spectra library.

Standard spectral lines are taken from NIST data and are useful for identifying emission peaks from
ionized gases or vapors. The line height is proportional to the relative probability of the transition causing
the emission. Only the strongest lines are shown.
