The temperature dependences of the proton spin-lattice, Tt, and spin-spin, T2, relaxation times of isotactic polypropylene films with different thermal histories and atactic fraction were investigated. A T~ minimum occurs for both melt-quenched and annealed samples at about 70Β°C. It shifts to lower
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
Proton spin-lattice, T~, and spin-spin, T 2, relaxation times of highly stretched isotactic polypropylene film were measured in the temperature range 40-110Β°C. There is a monotonical increase in T~, when measured at 40Β°C, as the stretching ratio is increased. A shorter T I, Tis, was observed for all
