NMR Chemical Shifts Beyond Numbers: Understanding Electronic Structures to a Reactivity Descriptor
NMR chemical shift is successfully used to identify the structure of molecules (and materials) making NMR an invaluable tool of characterizations. Because of its power to elucidate molecular structure, NMR interpretation is taught at an early stage, often in laboratory courses, even before one understands the fundamentals of spectroscopy and their selection rules. This lecture will concentrate on developing a detailed understanding of the origin of NMR chemical shift, and show how it can be used to reconstruct the electronic structure of molecules, particular organometallic intermediates. This lecture will illustrate why the symmetry of the angular momentum operator makes NMR a privileged spectroscopic descriptor of reactivity.
