12. 3He probe made by the Nalorac Co. The samples were not spun. When possible, shimming was done using the FID signal of the sample, although the intensity of the FID did not allow for a good adjustment of the field homogeneity.
13. The line width may actually be better than this. In many cases we were unable to achieve good shimming due to the low intensity of the FIDs in a single pulse.
14. This approximate comparison was made using the signal of the helium dissolved in glass as a reference, although field inhomogeneities and differences in the pressure of the gas in the NMR tubes may change the actual amounts.
