In previous posts on this BLOG, examples of  1H/2H and 12C/13C isotope effects were discussed.  The figure below shows an example of a 10B/11B isotope effect observed in the 19F NMR spectrum of tetrabutyl ammonium tetrafluorobarate.The spectrum clearly...
The pleasingly symmetric and narrow Lorentzian resonances in a high resolution NMR spectrum are truly things of stunning beauty, appreciated by all NMR spectroscopists. Their majesty depends on the homogeneity of the NMR magnet around the sample. Inhomogeneous...
Recently, I had a problem with an MAS probe which would no longer allow measurement of an MAS spinning frequency.  I thought it might be instructive to describe the device and the steps I took to solve the problem.  An MAS spin detection device includes...
