摘要：

The phenomenon of nuclear magnetic resonance (NMR) involves placing magnetically active nuclear spins embedded in a gas, liquid or solid phase in a constant, large and uniform magnetic field, causing the splitting of magnetic energy levels. The manipulation of multi-spin order by multi-pulse NMR methodologies leads to the measurement of cross-correlations, which affect the longitudinal relaxation including nuclear overhauser effect (NOE) via spectral densities at the Larmor frequency. They affect transverse relaxation via spectral densities at zero frequency as well.
