Abstract
Aluminium is the most abundant metal in the Earth's lithosphere and is present in many commercially important materials. Recent studies on its role in zeolites1 and proposed solar energy storage schemes involving aluminium salts2 have led to renewed interest in analytical methods capable of identifying and characterizing specific crystalline sites. In particular, new techniques are necessary which do not require single crystals. One such technique is Fourier transform nuclear quadrupole resonance (NQR) with pulsed field cycling3,4, and we report here on its application to the determination of specific 27 Al sites in model aluminium compounds, the alums.
