Well, this is a bit outdated, anyway, here it is. Lists frequencies, gyromagnetic ratios, natl. abundances, receptivities, magnetic and quadrupolar moments, and reference compounds of most NMR active nuclei.
The new IUPAC-recommendations, Pure Appl. Chem., 73, 2001, 1795-1818, by Harris, Becker, De Menezes, Goodfellow and Granger are incorporated. Download PalmNMRv3.1 and install it by unzipping and double clicking or opening in Palm Installer. The software is given away as-is. Please let me know if you find omissions or errors.
