Homonuclear dipolar-modulated chemical shift spectra in polycrystalline solids: the proton chemical shift tensor in CCl/sub 3/COOH. Technical report
Technical Report
·
OSTI ID:6388221
A single resonance, multiple pulse nuclear magnetic resonance experiment is proposed and demonstrated which produces a homonuclear dipolar modulation of a chemical shift powder pattern. The correlation generated between the homonuclear dipolar Hamiltonian and the chemical shift Hamiltonian can be used to determine the relative orientation of the chemical shift principal axis frame to the molecular frame. The experimental scheme is applied to determine the orientation of the proton-proton vector in a CCl/sub 3/COOH dimer relative to the chemical shift tensor of the hydrogen-bonded proton.
