β¦ Synopsis
The measurement of the dipolar interaction of 23 Na with hydroinformation all experiments were carried out with magnetic gen nuclei in glycerol solution is reported. The method, applied field strengths of 8.47 and 11.74 T. The instruments used previously to 7 Li (U. Eliav and G. Navon, J. Magn. Reson. A 123, were Bruker AMX 360 and ARX 500 operating at sodium 32 (1996)), is based on the measurement of the triple-quantum resonance frequencies of 95.3 and 132.4 MHz, respectively. relaxation time of 23 Na. Several models of motion are discussed.
