Spin diffusion biomolecules

Relaxation studies of biomolecules have involved measurements of the relaxation times of H, H, C and N spins. Proton spin diffusion is generally efficient for organic sohds so that pure compound gives single values for each of two relaxation times Tj and Tjp. Because of the specific nature of... 

The application of neutron spin-echo spectroscopy to the analysis of the slow dynamics of biomolecules is still in its infancy, but developing fast. The few published investigations either pertain to the diffusion of globular proteins in solution [332-334] or focus on the internal subnanosecond dynamics on the length scale, <10 A as measured on wet powders [335,336]. The latter regime overlaps with other quasi-elastic neutron scattering methods as backscattering and TOE spectrometry [337-339].
