Orientation of water in striated frog muscle.
Proton and deuterium nuclear magnetic resonance spectra of striated frog gastrocnemius muscle exhibit angular dependence, indicating partial orientation of water in the muscle. Nonzero static dipolar and quadrupolar interactions resulting from the anisotropic motion of the water molecules modulate the spin echo decays, contributing to their nonxponential behavior.
