## Spin-lattice relaxation times of 13C nuclei in pyridine and tetrahydrofurane have been measured at various temperatures. Mainly dipole-dipole interaction was found to influence the relaxation behaviour below 273°K. Spinrotation, which predominates at higher temperatures, was found to contribute
## Abstract Carbon‐13 NMR spin–lattice relaxation times, __T__~1~, and nuclear Overhauser effect data were obtained for neat tetra‐__n__‐octyltin at 22.5 and 100.6 MHz over a wide temperature range. __T__~1~ values were also measured at 25.16 MHz at pressures up to 211 MPa. The ambient‐pressure dat
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 70°C. It shifts to lower
Measurement of T2G, the Gaussian component of the spin-echo envelope of planar Cu nuclei in high-temperature superconductors, gives important information about the real part of the Cu electron spin susceptibility. In the traditional picture of the planar Cu echo decay, the internuclear coupling is a
