(27)Al NMR spectroscopy can be used for study of coordination and solvation in both aqueous and non-aqueous solutions. Various octahedral and tetrahedral aluminium complexes have been proved to exist in solution by (1)H and (27)Al NMR spectroscopy. (27)Al nuclear magnetic resonance (NMR) spectroscopy also can be used to determine thermodynamic properties of complexes in the solution. The formation of Al(OH)(4-n)(CH(3)OH)(n) (n=1, 2, 3 and 4) species through the reaction of aluminate anion with methanol has been investigated by (27)Al NMR spectroscopy. (27)Al NMR spectra reveal evidence for Al bound to one, two, three and four CH(3)OH, the production of aluminate species is affected by the MeOH/H(2)O. Results obtained from 2D EXSY experiments clearly confirm there are exchanges among the species.
铝核磁共振光谱可用于研究水溶液和非水溶液中的配位和溶剂化作用。通过氢核磁共振（¹H NMR）和铝核磁共振（²⁷Al NMR）光谱已证明溶液中存在各种八面体和四面体铝配合物。铝核磁共振（²⁷Al NMR）光谱还可用于测定溶液中配合物的热力学性质。通过铝核磁共振（²⁷Al NMR）光谱研究了铝酸根阴离子与甲醇反应生成Al(OH)(4 - n)(CH₃OH)ₙ（n = 1、2、3和4）物种的过程。铝核磁共振（²⁷Al NMR）光谱揭示了铝与一个、两个、三个和四个甲醇结合的证据，铝酸盐物种的生成受甲醇/水比例的影响。二维交换光谱（2D EXSY）实验结果清楚地证实了这些物种之间存在交换。
