Measurement of Hartmann-Hahn cross-polarization dynamics with quenching of proton T1 rho relaxation dependence.
A simple modification of the standard cross-polarization method designed for quenching the proton T1 rho dependence when studying polarization transfer is presented. It is demonstrated that by using this simple procedure, new and subtle details of cross-polarization dynamics, previously hidden by the T1 rho(1H) effect, can be observed in dipolar-coupled spin systems.
