We present a combined density functional theory, gauge-including atomic orbital (GIAO), in situ 13C MAS NMR, and in situ infrared study of acetylene adsorption on nano-sized MgO powder. Geometries were optimized using the hybrid B3LYP exchange-correl

In situ 13 C and 77 Se magic angle spinning (MAS) NMR was used to investigate the formation and reactivity of trialkylonium species on zeolite catalysts HZSM-5 and HY. Trimethyloxonium, trimethylsulfonium, and trimethylselenonium ions were all formed

This paper uses {sup 13}C solid-state NMR to study the chemistry of a variety of absorbates related to the methanol-to-gasoline process. This study has resulted in a better understanding of the chemical reaction occurring inside the zeolite HZSM-5 us

The reactions of acetylene on supported 10% Pt/alumina catalysts have been studied using variable temperature solid-state 13 C NMR with magic-angle spinning. In the vicinity of room temperature, high loadings of acetylene cyclotrimerize to form benze
