NIST Energy Levels of Hydrogen and Deuterium
Also known as Energy Levels of Hydrogen and Deuterium · NIST Standard Reference Database 142
This database provides theoretical values of energy levels of hydrogen and deuterium for principle quantum numbers n = 1 to 200 and all allowed orbital angular momenta l and total angular momenta j. The values are based on current knowledge of the revelant theoretical contributions including relativistic, quantum electrodynamic, recoil, and nuclear size effects. https://www.nist.gov/pml/energy-levels-hydrogen-and-deuterium
