In the following, we first give a brief description of the theory. The effective Hamiltonian for ST-selective rf pulses in the quadrupolar jolting frame explains the mechanism by which DCP can be achieved more efficiently than one-step CP. Both one-step and DCP via CT or ST are compared experimentally using histidine•HCl•H2O (hist) under 90 kHz MAS. The fast MAS has several advantages for the satellite-transition CP HETCOR experiments. First, it improves the line width and lengthens T2 as for all proton-detected MAS experiments. Second, fast spinning increases the effective rf field for the quadrupolar nuclei and leaves larger gaps among rotary resonance conditions 𝜔 1 H = nω1 (n =1/2,1,2..) for the protons . The large gaps help to reduce T1 contributions from the rotary resonance effect with the 1 H rf field used to match the HH CP conditions. Experimental optimizations and comparisons between 1 H/ 35 Cl single-and double-CP with the CT and ST will be presented. Near isotropic resolution from acquiring double-quantum ST HETCOR will be demonstrated for the spin S = 3/2 35 Cl nucleus.
