Controlling coherence using the internal structure of hard pi pulses
Yanqun Dong, R. G. Ramos, Dale Li +1
The tiny difference between hard pi pulses and their delta-function approximation can be exploited to control coherence. Variants on the magic echo that work despite a large spread…
Generating Unexpected Spin Echoes in Dipolar Solids with Pi Pulses
Dale Li, A. E. Dementyev, Yanqun Dong +2
NMR spin echo measurements of C-13 in C60, Y-89 in Y2O3, and Si-29 in silicon are shown to defy conventional expectations when more that one pi pulse is used. Multiple pi-pulse ech…

The Intrinsic Origin of Spin Echoes in Dipolar Solids Generated by Strong Pi Pulses
Dale Li, Yanqun Dong, R. G. Ramos +4
In spectroscopy, it is conventional to treat pulses much stronger than the linewidth as delta-functions. In NMR, this assumption leads to the prediction that pi pulses do not refoc…
