Abstract:We report on the effects of several commonly encountered instrumental artifacts on the buildup curves from a double-quantum-filtered nuclear magnetic resonance (NMR) pulse sequence for spin I ¼ 1 nuclei. In this work, the artifacts of finite pulse widths, radio frequency field inhomogeneity and pulse transients are studied. The buildup curves are calculated by numerically simulating the evolution of the spin density matrix under the Hamiltonian designed for the artifacts, and are then fit to a bi-exponential e… Show more
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
