Periodic Table

Every element, its ground-state electron configuration, and the spin, natural abundance and (where relevant) quadrupole moment of each NMR-active isotope. Click a tile to flip it over. Pairs well with the NMR frequency calculator.

† marks a long-lived radioactive isotope present in "natural" samples at trace abundance, rather than a truly stable nuclide. Quadrupole moment is not applicable for I = 1/2 nuclei. Gyromagnetic ratios and quadrupole moments are taken from the same reference set used in the frequency calculator, where available, supplemented with values derived from tabulated nuclear g-factors.
