“Electronic Structure of Atoms” Information System for Atomic Spectroscopy

Russia’s “Electronic Structure of Atoms” information and reference system for atomic spectroscopy is described. Its main characteristics and capabilities for supporting scientific research and training of specialists are explained. The data array contains more than 234 000 levels, with great attention given to experimental data and uniform filling across Z, including classified levels and transitions of all rare earth and transuranium elements and their ions. Original means of visualizing scientific data in the form of spectrograms, quantograms, and Grotrian diagrams are proposed. Presenting spectral data in the form of color interactive diagrams promotes understanding and analysis of the properties of an atomic system. In combination with its functionality, the use of spectral data from the “Electronic Structure of Atoms” information system is an effective way of solving different scientific problems and training specialists.
