Example Application of these Results

We will now see how to apply the equations derived above. As a first step, we notice that the 31P coupling is virtually isotropic. Thus, things can be simplified by taking the average of the 5/2,1/2 and 5/2,—1/2 assignments, etc.  

The next thing to notice is that the widely spaced features are very approximately equally spaced. This suggests that the g- and -matrix principal axes are non-coincident. You might think that a simple application of the above equations would suffice for a complete analysis. It is not quite so simple, and a nonlinear least-squares program is required.1,6 Table 7.4 shows the fitted parameters.
