The nuclear magnetic resonance of the nucleus in a single crystal was investigated at the temperature range of 200 K~410 K. The tendencies of temperature dependence of the nuclear quadrupole coupling for the two magnetically inequivalent Na(I) and Na(II) centers are found to be opposite to each other. The nuclear spin-lattice relaxation mechanism of in the crystal is investigated, and the result revealed that the Raman process is dominant in the temperature range investigated. The relaxation process of the nuclear spins was well described by a single exponential function in time. The values of the nuclei in the single crystal decreased with increasing temperature. The calculated activation energy for the is .
