摘要：
The zeolite SSZ-23 (STT) is the first zeolite found to contain channels bounded by seven and nine tetrahedral atom windows. A survey of the synthetic conditions needed to prepare SSZ-23 has been carried out, and the resulting materials characterized by synchrotron X-ray powder diffraction and magic-angle spinning NMR spectroscopy to obtain details of the long-range crystalline structure and short-range connectivity defects. The lattice energy minimized structure is in excellent agreement with the experimental results, and a comparison with other zeolites that have been simulated in this way is made.
