ABSTRACT: Experimental, theoretical and computational studies revealed that the characteristic time scales
involved in counterion dynamics in polyelectrolytes systems might span several orders of magnitude
ranging from subnanosecond times to time scales corresponding to acoustic-like phonon mode
frequencies, with an structural organization of counterions in charge density waves (CDWs). These
facts raise the possibility of observing Magnetic Resonance (MR) signals due to the movement of
counterions in polyelectrolytes. In case that this signal is detected in macroions or other biological
systems, like micelles, vesicles, organeles, etc. with rotational symmetry, this method opens a new
tool to measure with precission the counterions velocity.
