摘要

Increased 1H combined rotation and multiple pulse spectroscopy (CRAMPS) linewidths for protons within NH3+ groups in the solid state have been investigated by variable- temperature experiments. Linewidth variation with temperature can be correlated with specific molecular dynamic processes. With L-[15N]-alanine, both the NH3+ and CH3 group reorientations give rise to specific broadening of the respective CRAMPS signals as the ...
