## Abstract An approach to spinning sideband (SSB) separation of protonated and nonβprotonated carbons in slow spinning conditions via dipolar dephasing is proposed. This method offers two features: SSB spectral simplification, which greatly reduces the overlaps encountered in a usual SSB spectrum,
Chemically inequivalent carbons ortho to ether substituents are often seen in the solid-state I3C NMR spectra of aryl ether compounds. Calculation of the shielding caused by the steric, magnetic anisotropy, electric field and ring-current mechanisms demonstrates the importance of the electric field
