Received Date: 25 March 2002

Fund Project: We are gralcful to the support of the National Natural Science Foundation of China and The Ministry of Science and Technology of ChinaWe appreciate Dr. R. Fu (NHMFL, Tallahassee) for his kind liclp regarding the MQ MAS NMR experiments.

The elegant 2D multiquantum (MQ) MAS NMR has been applied to invcstigatc the coordination of Al atoms in SAPO-34. The results show that the effects of the template and/or water on the coordination of Al atoms are significanl, which lead to the formation of various Al species. Up to four kinds of Al species are distinctly resolved.
