Zusammenfassung
The concept of dipolar recoupling is introduced to H-1-H-1 NOESY experiments performed under HRMAS conditions. Dipole- dipole couplings are selectively recoupled during the mixing period, while MAS ensures high resolution in the spectral dimensions. Incoherent dipolar exchange is replaced by amplified coherent processes, such that time scales for polarization transfer are shortened, and dipolar double-quantum techniques become applicable. In this way, dipole-dipole couplings, as well as J-couplings, can be individually measured.
