Progress in Nuclear Magnetic Resonance Spectroscopy
Abstract
Publisher Summary This chapter throws focuses on thallium nuclear magnetic resonance (NMR) spectroscopy. The advent of pulsed Fourier transform (FT) nuclear magnetic resonance spectroscopy has opened the periodic table of the elements to investigation in an extraordinary manner. Any nuclide with spin can now be observed routinely in the NMR experiment. Moreover, it is important to note that NMR experiments had been performed with about 30 elements in the solid, liquid, or gas phase. Thallium is particularly well suited for the NMR experiment because of its intrinsic nuclear properties. Thallium has two isotopes—203TI and 205TI., Thallium205 is the most receptive heavy metal spin of nucleus by a factor of 30 over 119Sn, which is the second most receptive heavy metal. A summary of the pertinent nuclear properties for the 203Tl and 205TI nuclides is provided in the chapter. Thallium NMR spectroscopy is a very useful technique for investigating a wide variety of chemical and physical interactions in the solid and solution states. Tl(I) ion is a good replacement for the Na(I) and K(I) ions in many biological systems, thus, providing a convenient spectroscopic alternative for the study of phenomena such as ion transport across membranes and the activation and regulation of enzymes.
