Fundamentals of Pulsed Nitrogen-14 Quadrupole Resonance,rtening the repetition time. Finally it has been possible to define proper phase cycles in view of measuring relaxation times (T. and T.) by a two-pulse sequence. In all cases, experimental verifications were performed in order to assess this methodology.

Modeling of Qr Sensors for Optimized Explosives Detection,edict ROC curves for the QR detector and evaluate trade-offs between experimental parameters, sample characteristics, data processing, and hardware features of the detector. Numerical and experimental results are presented to validate our models, and demonstrate their usefulness for QR sensor design

14N Nuclear Quadrupole Resonance Signals in Paranitrotoluene and Trinitrotoluene. Spin-Lock Spin-Ec applies mainly to trinitrotoluene, with 12 resonance frequencies between 837 and 871 kHz. Our frequency dependent investigation shows that the signal intensity as well as the effective spinspin relaxation time varies substantially with irradiation frequency in both samples. We provide a theoretical
