The magnetic field dependence of the water-proton spin-lattice relaxation rate (1/T(1)) in tissues results from magnetic coupling to the protons of the rotationally immobilized components of the tissue. As a consequence, the magnetic field dependence of the water-proton (1/T(1)) is a scaled report o

The intensities of saturation-transfer EPR (ST-EPR) spectra from nitroxyl spin labels have proved a sensitive means for studying slow exchange processes (both Heisenberg spin exchange and physical/chemical exchange) and weak interactions with paramagnetic ions, via the dependence on the effective sp
Temperature-dependent con formational transitions of deoxyoligonucleotides have been monitored by measuring 3 1 P chemical shifts, spin-lattice relaxation times ( T I ) , and :31P-IHI nuclear Overhauser enhancements (NOES). The measured NOE ranged from 30 to 80% compared to the theoretical maximum o
Recent developments in the mathematical solution of nuclear magnetic ( ) resonance NMR relaxation equations describing rotational motion allow investigators to determine correlation times, , on the nanosecond time scale.

## Abstract A molecular theory is presented for the fieldβdependent spinβlattice relaxation time of water in tissue. The theory attributes the large relaxation enhancement observed at low frequencies to intermediary protons in labile groups or internal water molecules that act as relaxation sinks f
