NMR spectroscopy has proven to be an invaluable tool in structure determination of hydrogenated fullerenes ever since the first synthesis of C60H36 (Haufler et al. 1990) and the first structure determination by NMR was reported for C60H2 by Henderson and Cahill in 1993 (Henderson and Cahill 1993). Today, a multitude of both one- and two-dimensional NMR experiments are available for this purpose. Recent developments in NMR technology with higher magnetic field strengths and cryoprobes have dramatically increased the sensitivity and improved the usefulness of NMR in this field even further. 

From these results, it is evident that QCPMG experiments may be performed when the second-order quadrupolar effect is adequately small. In the present calculations, the CQ-limit for the QCPMG spectra is around 750 kHz at 14.1 T but this limit is of course higher at higher magnetic field strengths. 

The development of higher magnetic field strength has also been vital to improve both resolution of NMR spectra (proportional to Bo", where n is the dimensionality of the NMR experiment) and sensitivity (proportional to Bo ). 

The development of solid-state NMR as a successful tool for the characterization of zeolitic and other porous materials has been tremendous during the last two decades. Considerable progress has been made with respect to higher magnetic field strengths, faster... 

In Check it 3.2.1.1 the correct measurement of two sets of signals is demonstrated. In addition the effect of the number of time domain data points TD on the digital resolution using the same spectral width recorded at higher magnetic field strengths is illustrated.
