Reduction of unwanted signals in J-resolved spectroscopy

  • Summary


Method for reducing unwanted signals derived from “strong couplings”

Multiple scan method:
Multiple scan method:
All the unwanted signals can be reduced,  though signal may decay due to multiple accumulation and T2 relaxation during tp.
Double Spin-Echo method:
Double Spin-Echo method:
Unwanted signals are removed by symmetrization of a single-scan spectrum,  though signals happening to appear  symmetrically cannot be removed.
Single pulse method


The present results are based on the method reported in:
M. J. Thrippleton, R. A. E. Edden, J. Keeler, J. Magn. Reson., 174, 97, (2005).
