Short summary

The transfer of polarization from protons to half-integer spin quadrupolar nuclei provides insights into the proximities between these nuclei. We analyse the best transfers at 20 and 62 kHz MAS obtained with RINEPT and PRESTO recouplings using adiabatic or composite π pulses. The 1H magnetization is best transferred using PRESTO-R22,7,2 (180) or -R16,6,7 (270,90) at 20 or 62 kHz MAS, respectively, and RINEPT-SR4,2,1 (270,90).
