"Practical aspects of nuclear quadrupole resonance as a method for the " by Lewis Robertson

The capability to accurately and safely identify security sensitive substances is a tool of paramount importance in defence and security industries all over the world. Nuclear Quadrupole Resonance (NQR) is a radio frequency (RF) spectroscopic technique that probes the nuclear spin states of a material and is uniquely felicitous to the detection of solid-state security sensitive substances. This is because the technique does not demand any sample preparation or direct contact with the target substance. It is a highly specific detection method due to the sensitivity of quadrupolar resonances to the electronic environment surrounding the target nucleus. It also allows for bulk measurements of materials as the magnetic field pulses used to excite the target nucleus are transparent to non-conductive materials. In contrast to its close phenomenological counterpart Nuclear Magnetic Resonance (NMR), a large external magnetic field is not required, making NQR spectrometers suitable for applica ....
