Dynamic balancing in NMR double rotor system.
An exact solution to the problem of dynamic balancing in a NMR double rotor system is presented. This will enable one to perform high speed spinning about two intersecting axes. Double rotation is used in solid state NMR to average away second-order broadening, thus enhancing the resolution of spectra from quadrupolar nuclei in solid state NMR. An exact expression for imbalance due to asymmetric distribution of weights about the rotation axes is provided.
