HR-MAS NMR Spectroscopy in Material Science

Schematic of a HR-MAS stator with a magic angle gradient along the rotor spinning axis. 

The gradient 2D 1 H HR-MAS NMR COSY spectrum for the ionic liquid [MBPyrr] + [TFSI] - 







The 1 H HR-MAS NMR of the ionic liquid [MBPyrr] + TFSI - at 298K as a A) neat liquid and B)







Pictorial representation of the gradient produced along the magic angle of the rotor. B) The decay of two different water signals found in a 1N methanol solution of an AEM membrane with increasing gradient strength. Gradient strength values (G/cm) are shown above the stack plot.
