Determination of 27Al quadrupolar coupling parameters and of metallic aluminium in commercial lithium aluminium hydride by 27Al MAS NMR
Abstract
The 27Al quadrupolar coupling parameters (CQ= 3.90 MHz and η= 0.30) and a high content of metallic aluminium (16 ± 2 atom %) have been determined for commercial LiAlH4 using 27Al MAS NMR spectroscopy.
