Frequency shift of gradient-echo MRI provides valuable information for assessing brain
tissues. Recent studies suggest that the frequency and susceptibility contrast depend on …

It has recently been shown that the degree of alignment of macromolecules in an aqueous
dilute liquid crystalline medium of bicelles is sufficient to permit accurate values of residual …

Residual dipolar couplings arising from small degrees of align- tein–DNA complexes, as
opposed to proteins alone, is sim-ment of molecules in a magnetic field provide unique long …

Conspectus Many multidomain proteins and ribonucleic acids consist of domains that
autonomously fold and that are linked together by flexible junctions. This architectural …

Nuclear Magnetic Resonance is particularly sensitive to the electronic structure of matter
and is thus a powerful tool to characterize in-depth the magnetic properties of a system …

Gradient-echo MRI has revealed anisotropic magnetic susceptibility in the brain white
matter. This magnetic susceptibility anisotropy can be measured and characterized with …

Dipolar magnetic field effects have been detected in the NMR spectra of coronene and
methylpyropheophorbide in liquid solution. These effects arise from the partial molecular …

The backbone 15N− 1H 1 J values have been measured for oxidized and reduced
cytochrome b 5 at 500 and 800 MHz. Their field dependence, due to increasing partial …

Lanthanides may substitute calcium in calcium-binding proteins, such as, for instance, EF-
hand proteins. Paramagnetic lanthanides are capable of orienting the protein in high …

In this Account recently developed aspects of the NMR of “partially oriented” molecules will
be dis-cussed. The partial orientation is dynamic in nature, not static, since it is observed in …
