- Abstract
- Spin–lattice relaxation rates (T1−1) for 7Li and 133Cs nuclear magnetic resonance in the nonlinear optical crystal CsLiB6O10 were measured in the temperature range 20–300 K. The dominant relaxation of this crystal in the whole temperature investigated is due to quadrupolar interaction. 7Li spin–lattice relaxation time on the CsLiB6O10 yielded a minimum, attributed to the effect of molecular motion. These experiments have been analyzed by BPP theory, and the activation energy for the molecular motion was determined to be 21.19 kJ/mol. T1−1 for the 133Cs nucleus is well described with the simple power law of T1−1=ATk+B, where T is the temperature. The measured relaxation rate was found to be proportional to the T2. The temperature dependence of the relaxation rates for the 133Cs nucleus in a CsLiB6O10 single crystal is in accordance with a Raman process.
