    • NIST Handbook of Basic Atomic Spectroscopic Data - SRD 108

    Metadata Updated: September 30, 2025

    This handbook provides a selection of the most important and frequently used atomic spectroscopic data in an easily accessible format. The compilation includes energy levels, ionization energies, wavelengths, line intensities, transition probabilities, and spectrum assignments for the neutral and singly-ionized atoms of all elements hydrogen through einsteinium (Z = 1-99), given in separate tables for each element. It includes approximately 12,000 spectral lines of all elements. Bibliographic references are provided for all data.
