We propose high-resolution magic angle spinning as a radical method for the suppression of dipolar field effects in liquid NMR. This technique works for any sample shape and any spatial distribution of nuclear magnetization. Furthermore, it removes any possibility of spectral clustering or instabili
By the application of an external electric field to a polar liquid the molecules are slightly nlignecl. The dipole-dipole interaction between the nuclear spins is then not averaged out and the NhlR spectrum is modified. Results are presented for nitrobenoene and 2.4-dimethylnitrot,enzene.
