摘要：

Zeolite ZSM-23 has been studied by one- and two-dimensional Si-29 MAS n.m.r. spectroscopy. The results reveal that there are twelve inequivalent T-sites with equal occupancies in the unit cell. A two-dimensional INADEQUATE experiment yielded the complete Si-O-Si connectivity pattern but this could not be fit with either of the two proposed space groups.
