      Tin, with its three common isotopes 116 Sn, 118 Sn and 120 Sn, is among the easiest elements to detect and analyze by NMR spectroscopy, and its chemical shifts are referenced against SnMe 4. This large number of stable isotopes is thought to be a direct result of the atomic number 50, a quot;magic numberquot; in nuclear physics. Tin also occurs in 29
