Magnitudes and mutual orientations of dipolar and shielding interaction tensors determined from the orientation dependence of spinning sidebands of slowly rotating powder samples.
It is shown that the orientation dependence of spinning sidebands of slowly rotating solids can be exploited to determine with good precision the heteronuclear bond distances and mutual orientation of dipolar and shielding tensors from a single dipolar modulated chemical shift anisotropy spectrum. The method is based on the dynamics of polarization transfer in the initial period of tens of microseconds, and may be useful in solids with relatively isolated groups of spins.
