	abstract = {AlPO-36, the parent member of the ATS, molecular sieve structure type, has been synthesized hydrothermally from gels containing only Al and P oxides. Four series of syntheses were carried out to determine the best conditions for the preparation of AlPO-36 free of AlPO-H3, Characterization of the synthesis products was performed using X-ray diffraction (XRD), chemical analysis, scanning electron microscopy (SEM), N-2 adsorption, X-ray photoelectron spectroscopy (XPS) and Al-27 and P-31 MAS NMR. X-ray powder diffraction patterns are comparable to those previously reported for MAPO-36. (C) 1999 Elsevier Science B.V. All rights reserved.},

	abstract = {Al-27/P-31 solid-state n.m.r. connectivity experiments were used to investigate the structure of the molecular sieve AlPO4-5 hydrated with D2O. Hydration with D2O resulted in an increased efficiency of coherence transfer from octahedral Al-27 to P-31 compared with hydration with H2O. The experiments prove directly that both the tetrahedral aluminum and the octahedral aluminum formed upon hydration are connected to phosphorus in the framework. The two-dimensional Al-27 {\textendash}> P-31 transferred-echo double-resonance and cross-polarization experiments show a downfield offset of the octahedral Al-27 correlation from the tetrahedral Al-27 correlation, consistent with the growth of a downfield shoulder on the P-31 resonance as water is incorporated into the lattice.},

	abstract = {In this work we present the results of a systematic investigation of a set of dipolar-based Al-27 {\textendash}> Si-29 connectivity experiments for a series: of representative zeolite molecular sieve frameworks: zeolites A, X, Y, and Omega. Coherence transfer from quadrupolar Al-27 (I = 5/2) to Si-29 (I = 1/2) nuclei through cross polarization and transferred-echo double-resonance (TEDOR) experiments is. observed, and an experimental investigation of the parameters controlling the efficiency of both experiments is presented. Rotational-echo double-resonance (REDOR) and dipolar-dephasing difference experiments are also demonstrated. These experiments utilize the heteronuclear dipolar couplings, whose magnitudes are proportional to the inverse third power of the internuclear distance and are therefore extremely sensitive to the separation of the coupled spins. In addition, we demonstrate that for these dipolar-based experiments, there is a relative enhancement of a given resonance which is approximately linear with the number of aluminum atoms in the neighboring tetrahedral sites. Two-dimensional extensions of the cross-polarization and TEDOR experiments are also possible and will be of use for complex mixtures or where several resonances are observable in the one-dimensional spectra of the two nuclei.},
