- 論文の詳細を見る
Significant transient ^<13>C-^1H nuclear Overhauser effect (NOE) is observed in liquid crystal, and is explained by a local ^<13>C-^1H dipole-dipole interaction and relaxation. Solomon's classical two-pulse experiment gives a significant maximum in signal intensity of 2.5 times the equilibrium magnetization, and also gives a way of estimating zero-quantum transition probability for a dipole-coupled ^<13>C-^1H pair. The conventional inversion recovery sequence is recommended for the experimental determination of ^<13>C spin-lattice relaxation rates. Magnetization recovery after the Hartmann-Hahn signal enhancement deviates strongly from exponential behavior. Experimental data are shown for an antiferroelectric chiral smectic liquid crystal MHPOBC.
