Increased 1H combined rotation and multiple pulse spectroscopy (CRAMPS) linewidths for protons within NH3(1+) 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(1+) and CH3 group reorientations give rise to specific broadening of the respective CRAMPS signals as the temperature is lowered.Such dynamic processes may be more important than 14N-1H quadrupolar-modified dipolar broadening in determining NH3(1+) proton lineshapes.
