摘要：

A new high temperature NMR probe assembly using CO2 laser as heating system enables a better description of the high temperature phase transitions of LiNaSo4 from room temperature to the liquid state (940 K). Linewidth and T1 relaxation time measurements give new information about the cationic diffusion which begins at least 400 degrees below the superionic transition. At this transition a double resonance mechanism between cations jumps and SO4 rotations is proposed. © 1990.
