Investigating Homonuclear Broadening in NQR with Carr-Purcell Meiboom-Gill Performed on p-Chloroanilng in a substance without a strong heteronuclear broadening component. This new work could expand the number of samples for which those conclusions are applicable, creating more opportunities to use NQR to measure homonuclear dipolar coupling for both material characterization and determining efficient detection procedures.

Conference proceedings 2014 quadrupole resonance (NQR) is unique in many ways. It operates in a safe AM radio frequency range, and it can remotely detect unique “fingerprint” (NQR spectrum) of many explosives, such as TNT or RDX. As such, the detection of target does not depend on the shape or material of the container, or th

NMR-Based Liquid Explosives Detector: Advantages and Disadvantages of Different Configurationsrmanent magnet with a strong magnetic field gradient, and a permanent magnet where the sample is placed in a homogeneous field. Measurements of a series of liquid samples that can be encountered in hand luggage are presented. We discuss the advantages and disadvantages of different detector configurations.
