METHODS OF USING COMBINED FORWARD AND BACKWARD SAMPLING OF NUCLEAR MAGNETIC RESONANCE TIME DOMAIN FOR MEASUREMENT OF SECONDARY PHASE SHIFTS, DETECTION OF ABSORPTION MODE SIGNALS DEVOID OF DISPERSIVE COMPONENTS, AND/OR OPTIMIZATION OF NUCLEAR MAGNETIC RESONANCE EXPERIMENTS

摘要

The present invention relates to a method of conducting an N-dimensional nuclear magnetic resonance (NMR) experiment in a phase-sensitive manner by the use of forward and backward sampling of time domain shifted by a primary phase shift under conditions effective to measure time domain amplitudes and secondary phase shifts. The present invention also relates to methods of conducting an N-dimensional NMR experiment in a phase-sensitive manner by the use of dual forward and backward sampling of time domain shifted by a primary phase shift under conditions effective to measure secondary phase shifts or at least partially cancel dispersive and quadrature image signal components arising in the frequency domain from secondary phase shifts.
