Jun 01, · INTRODUCTION. Zero-field nuclear magnetic resonance (NMR) is an alternative magnetic resonance modality in which nuclear spin information is measured in the absence of applied magnetic field (1–5) and serves as a complementary analysis tool to conventional high-field rangelyautomuseum.com-field NMR experiments regularly achieve nuclear spin coherence times longer than 10 s without using Cited by: Nuclear magnetic resonance (NMR) is a spec-troscopic technique that detects the energy ab-sorbed by changes in the nuclear spin state. The application of NMR spectroscopy to the study of proteins and nucleic acids has provided unique in-formation on the dynamics and chemical kinetics of these systems. One important feature of NMR.
Moisture measurements using a pulsed nuclear magnetic resonance technique were initiated to support a detonator corrosion investigation. Results using this technique led to process changes which decreased corrosion rates. This technique is presently used routinely to monitor production samples and aid in process development of new materials. 1 Nuclear Magnetic Resonance Before describing how Nuclear Magnetic Resonance (NMR) techniques can be used to implement quantum computation I will begin by outlining the basics of NMR. Introduction Nuclear Magnetic Resonance (NMR) is the study of the direct transitions between the Zeeman levels of an atomic nucleus in a magnetic ﬁeld [1–7].
