Principal values of the 13C chemical shift tensor were obtained for the 15 carbons of solid caryophyllene oxide using an improved PHORMAT NMR analysis. The improvements include TIGER processing and improved proton decoupling. TIGER is an alternative to Fourier methods and shortens 2D data collection
The potential of heteronuclear MAS NMR spectroscopy for the characterization of (15)N chemical shift (CS) tensors in multiply labeled systems has been illustrated, in one of the first studies of this type, by a measurement of the chemical shift tensor magnitude and orientation in the molecular frame
The results of various 15 N solid-state NMR experiments perin the molecular principal axis system (PAS) is necessary formed on solid samples of doubly 15 N-labeled 3,5-dimethylpyrafor the analysis of several solid-state NMR experiments, e.g., zole, 5-methyl-3-phenylpyrazole, (PMP), and 3,5-diphenylp
Nuclear Magnetic Resonance (NMR) chemical shifts(Ξ΄) for elements in solids may often be approached by ab initio cluster calculations. We employ this technique to investigate the influence of structural alterations on the 15 N and 11 B chemical shifts in boron nitrides-in both hexagonal and cubic mod
