Water proton transverse relaxation times (T 2 ) and self-diffusion coefficients (D) were measured in randomly oriented hydrated collagen fibers. Three T 2 relaxation times were discerned indicating the presence of at least three water fractions in the collagen sample. The D values associated with ea
Theoretical models for motionally driven spin diffusion are compared and applied to spins S = (1/2) and S = 1. Their predictions are quantitatively corroborated by experiments on a single crystal of deuterated biphenyl. In this system, a molecular flip process drives spin diffusion and makes it stro
## Abstract The role of water of hydration in proton relaxation in tissues as exemplified by hydrated collagen in beef tendon was studied as a function of temperature from β40Β° to 37Β°C by using crossβrelaxation spectroscopy. Experimental data were fitted to a simple binary spinβbath model. The outc
