Dipolar Interactions in Molecules Aligned by Strong AC Electric Fields

Effect of iodine on morphology changes of spray deposited nanocrystalline CdSe:I, CdTe:I and HgTe:I thin films

“…CdTe nanoparticles are also expected to have a high dipole moment. Although self-assembled (chain-type) structure formation is known for magnetic nanoparticles [32], nonmagnetic neutral molecules with high dipole moments also display the same effect in external fields [33]. Hence in our case we can also associate the dipole-dipole interaction of the iodine-doped nanoparticles with the creation of nanofibrous structures.…”

Determination of the three-dimensional structure for weakly aligned biomolecules by NMR spectroscopy

“…It has been proposed 165,166 to use an alternating pulse electric field synchronised with a sequence of radiofrequency pulses. In this case, multidimensional NMR experiments can be carried out with the electric field being switched on and off at particular time instants.…”

Structure determination of aligned systems by solid-state NMR magic angle spinning methods

“…A small degree of orientation can be induced in a solution sample via the effect of a strong electric or magnetic field on an aligning media or the sample itself if sufficient anisotropic magnetic or electric susceptibility exists. A solute under either condition can have an order parameter of less than 1% due to incomplete motional averaging by way of slightly anisotropic molecular tumbling, which is a sufficient degree of alignment for oriented solution NMR experiments [9][10][11][12][13]. This approach has had tremendous impact on the quality of solution NMR structures.…”
