Table 3. Gyromagnetic Ratios for Biologically Relevant Nuclei |

In the case of proton-proton interactions, both nuclei S and /will have the same gyromagnetic ratios, and an implication of the Equation (4) then is that there is an upper limit of 50% on the nOe obtainable, whatever the distance between nuclei S and I. This means that the observation of an nOe between two nuclei does not necessarily mean they are spatially close to one another, and nOe results must therefore be interpreted with caution. Similarly, as will be seen later, the absence of nOe between two nuclei does not necessarily mean they are far apart. In the case of heteronuclear nOe, since the gyromagnetic ratio of proton (yv) is four times the gyromagnetic ratio of carbon y,), js/ jt can be four times greater than that obtainable in homonuclear nOe.

Sauer et al. [185] determined the gyromagnetic ratio g(9/2)/g(7/2) and the magnetic moment of the 6.2 keV level in Ta in two ways, (1) from the Zeeman split velocity spectrum of a metal source in a longitudinal field versus a Ta [Pg.298]
