摘要：
The effects of homonuclear dipole couplings may be reintroduced into magic angle spinning nuclear magnetic resonance (NMR) spectra by judiciously spaced pi pulse trains. This recoupling phenomenon occurs over a wide range of chemical shift differences and sample rotation speeds. We present results of magnetization exchange experiments exploiting the broad band recoupling effect, and propose a theoretical description in which pulse-assisted dipolar recoupling may be understood as a form of compensated rotational resonance.
