摘要：

The 3D lattice connectivities in zeolites ZSM-12 and KZ-2 have been investigated by natural-abundance 29Si/29Si COSY and INADEQUATE 2D NMR experiments. In both cases the results are in exact agreement with the lattice structures, the INADEQUATE experiment being particularly successful and detecting all of the connectivities. Inaddition, it is possible to observe directly the scalar J couplings that are in the range of 10-15 Hz. The approach is of quite general applicability and may be extended to other 3D structures. © 1990, American Chemical Society. All rights reserved.
