Database of multiplicities and magnetogyric ratios for stable and long-lived isotopes with non-zero spin. Syntax:
where the name of the isotope is given in the standard way, e.g. 13C or 195Pt. High-spin electrons may be requested by supplying 'E' followed by multiplicity - 'E3' would request a spin-1 electron and so forth.
Note: data with no source specified was sourced from Google and should be double-checked before running production calculations.
