What is the Periodic Table Showing? Periodicity

The INTERNET Database of Periodic Tables

There are thousands of periodic tables in web space, but this is the only comprehensive database of periodic tables & periodic system formulations. If you know of an interesting periodic table that is missing, please contact the database curator: Mark R. Leach Ph.D. The database holds information on periodic tables, the discovery of the elements, the elucidation of atomic weights and the discovery of atomic structure (and much, much more).

NMR Nuclear Spin Periodic Table(s)

An nuclear magnetic resonance (NMR) spectroscopy periodic table giving information the nuclear spins, etc., of the chemical elements, from the Bruker corporation website:

And, another:

 

The range of NMR active nuclei observable on a particular instrument is, in part, a function of the configuration of the spectrometer and the choice of available probes. The periodic tables below identify the nuclei that have resonance frequencies within the detection range of the Lake Forest College Inova and the EFT-60 NMR spectrometers.

The nuclei in red are I=1/2 and yield spectra with narrow, non-overlapping resonances. The nuclei in blue have quadrapolar moments and may give rise to broad or very broad resonances in their spectra.
