Description
By 2H, 11B and 133Cs NMR pulsed method polycrystal borohydrides MBH4 (M=Na, Rb, Cs and Bu4N) and NaBD4 in the temperature range of 145-310 K have been investigated. The values of activation energy (Ea) and preexpotential multiplier of [BH4]- and [BD4]- anion reorientation motion are determined. The values of Ea decrease with the growth of unit cell volume
