The Brønsted acidity of H-mordenite (H-MOR) and H-b with similar Si/Al ratios has been characterized by conventional multinuclear solid-state NMR. 1 H/ 27 Al TRAPDOR NMR showed the presence of at least two different types of Brønsted acid sites in H-b. On the other hand, only a single 1 H resonance

## Abstract The reaction mechanism of the model cytochrome P450‐mediated desulfuration of thiophosphoryl trifluoride, trimethylphosphine sulfide, and trimethyl phosphorothionate was examined by the semiempirical MNDO‐PM3 molecular orbital method. The proposed pathways, involving initial formation o
