Explanation of the Spectra of Metals of the Second Group

Abstract

THE explanation of the complicated spectra of elements is now making rapid strides, thanks to the more complete and accurate knowledge of the structure of the atom which we owe to Stoner, and the development of the quantum principles of combination which we owe to Russell, Pauli, Heisenberg, and Hund. The latter authors have so far confined their attention to the explanation of the fundamental terms of the spectra. But the principles can be extended for finding out the higher members as well. The following is a brief sketch:
