A Motivation and Methodology

For almost a quarter of a century the words nuclear magnetic resonance were synonymous with proton measurements. During this period the literature abounded with a seemingly infinite variety of NHR studies concerned primarily with carbon chemistry. Occasionally a 

The second asset offered by both C and P concerns the sensitivity of both the chemical shift, 6L, and the coupling constant, J(M,L), (L = or P) to structural change. Whereas the proton 

It is reasonable to assume that there exists some Hq field, generated by a super conducting magnet, which will invalidate this statement. 

Before proceeding further a few words concerned with the 

The methodology involved in 3q nmr has been extensively reviewed. See for example Levy G., (ed.) Topics in Carbon-13 NMR Spectroscopy, Vols. 1 and 2, New York Wiley Interscience.
