“…Electrophoretic NMR is by now a reasonably old technique, being first suggested in the late 1960s (75)(76)(77), and later developed into a practicable method in chemistry mainly by Johnson and co-workers (78 -86). Some applications have also been presented by some of the present authors (87)(88)(89)(90) as well as by others.…”

Surfactant molecules are amphipathic and posses complicated solution chemistry and self-assembly properties. In addition to being of enormous practical significance, the physical characterization of surfactant systems presents a rich area of condensed matter physics. This article focuses on the application and interpretation of the commonly used NMR approaches for probing these systems. In particular, the use of NMR relaxation, diffusometry and, more briefly, electrophoretic NMR to determine characteristics such as micellar size and structure, ion-binding and solubilization are considered. The application of these NMR techniques is illustrated by a number of pertinent examples.

“…Such a configuration was used in the pioneering ENMR experiments carried out on an electromagnetic NMR spectrometer where the DC electric field was perpendicular to the B 0 direction (12)(13)(14). The electric current (I e ) not parallel to B 0 produces FIG.…”

“…In a usual arrangement for ENMR, the sample is placed in a glass U-tube (17,18) with two Pt wires as electrodes immersed into the solution residing in the two upward tube branches, respectively. Hence, gas that develops at the electrodes during the application of electrophoretic current has exit ways upwards (but can be trapped due to surface tension effects).…”

Artefacts in electrophoretic NMR experiments are investigated in detail. We identify electroosmosis, sample heating, and gas development on the electrodes as main error sources and suggest experimental strategies and setups to suppress their influence on the monitored electrophoretic mobilities. We hereby demonstrate essentially artefact-free experiments up to currents and electric fields 3 mA and 70 V/cm, respectively.
