 Title    Lithium-tetrahydroaluminat in Ether: eine NMR-Untersuchung Lithiumtetrahydroaluminate in Ether: an NMR Study  
 Abstract    Ether solutions of LiAlH4 have been investigated by 27 Al and 7 Li magnetic resonance in the concentration range 3.75-0.0075 M. The Al-signal shows a fine structure due to Al-H coupling only at concentrations below 0.15 M. The observed chemical shift 27 Al is only slightly concentration dependent. The line width of the 27 A1 signal, which is inversely proportional to T2*, reaches a minimum value at a concentration where the best resolution of the 27 A1 quintet is observed. This, however, is not matched by the 7 Li line width whose minimum value was found at a somewhat higher concentration. The results are consistent with multiple ion formation at the higher concentrations and with an ion pair at low concentrations.
