spectral line| Dark line visible in an absorption spectrum, or one of the bright lines that make up an emission spectrum. Spectral lines are caused by the transfer of an electron in an atom from one energy level to another; strong lines are produced at levels at which such transfer occurs easily, weak where it occurs with difficulty. Ionization of certain elements can affect such transfers and cause problems in spectral analysis. |
