This app displays a simple interactive table of properties for the NMR active isotopes. Properties displayed are element and isotope symbol, nuclear spin, natural abundance, gyromagnetic ratio, electric quadrupole moment, Larmor frequency, and dipolar coupling. Table can be sorted on any column. The magnetic field strength can be adjusted to determine the Larmor frequency. Dipolar couplings can be adjusted for different isotopes and internuclear distances. Additional filtering for even and odd atomic number isotopes, and for nuclear spin values.
