Adiabatic cross-polarization via intermediate dipolar-ordered state.
It is experimentally demonstrated that an adiabatic demagnetization-remagnetization in the laboratory frame, where the Zeeman order of abundant nuclei is first adiabatically converted into the dipolar order, and then, into the Zeeman order of rare nuclei, can significantly increase polarization of rare nuclei compared to the conventional cross-polarization technique.
