Gradient pyramid coherence
WebThe starting point of the wavelet pyramid is the identification of the Laplace-complex gradient, which characterizes the complete family of shift-invariant, scale-invariant, and … Web4 Coherence Selection: Phase Cycling and Gradient Pulses A multiple-pulse NMR experiment is designed to manipulate the spins in a certain carefully defined way so as to produce a particular spectrum. However, a given pulse sequence usually can affect the spins in several different ways and as a result the final spectrum may contain resonances

WebA coherence in NMR is a physical state when many spins line up and rotate with the same speed around the magnetic field direction in the classical sense. Quantum mechanically, … WebPulsed field gradients (PFGs), also known as gradient enhanced spectroscopy (GES), can be used to achieve coherence selection and minimize the need for extensive phase cycling. In PFG spectroscopy a large z -gradient is introduced along the sample's vertical axis (magnitude approximately 0.1–0.5 T m −1 and duration approximately 1 ms ...
