β¦ Synopsis
The spin-lnttice rclaxltion of I% nuclei in inorganic ions is governed by inter-nnd intramoleculnl dipole-dipole and shift anisotropy intcrnctions at lowzr tcmpcrntures and by the spin-rotation interaction at higher temperatures.
The mensured relnxttion rntes lcsd to rcasonablc rnlues for the 15~ spin-rotation coupling constnnt.

## Spin-lattice relaxation times of t3C nuclei in organic compounds have been measured in a wide temperature range. The dipole-dipole interaction with protons is predominant at lower temperatures and the spin-rotation interaction at higher temperatures. Both the measured relaxation times and r3C c
The validity of the formalism for the off-resonance rotating-frame spin-lattice relaxation experiment applicable to spin-1 quadrupolar nuclei was experimentally examined by considering two model systems, deuterated glycerol and deuterated benzene in castor oil, at different temperatures. When approp
