Question

Write the Regularities in complex spectra.​

Answer 1

Regularities in complex spectra of iron group elements are illustrated as regards iso-electronic and iso-ionic sequences as well as iso-elemental comparisons.recently with the discovery of regularities in the complex spectra which characterize many of the chemical elements. represented by a single value; all energized states are double so that the doublet structures in the arc spectra of these elements are thereby explained.
