Detection of Selected Chemical Substances by Means of Nuclear Quadrupole Resonance Detection of Selected Chemical Substances by Means of Nuclear Quadrupole Resonance

Popis výsledku v původním jazyce

Nuclear Quadrupole Resonance (NQR) is an advanced diagnostic method for the spectroscopy of solid state substances. NQR exploits the presence of the electrical quadrupole moment of the atomic nuclei of certain isotopes. A broad set of substances, both inorganic and organic, have their quadrupole resonance in the range of ones to tens of MHz. An important fact is that recognizable quadrupole resonance can be detected in the case of substances present in explosives, drugs, and medicaments. The utilization of NQR constitutes a promising perspective for non-contact, non-destructive diagnostics in chemical research, material science, and security applications. A compact experimental NQR spectrometer has been built at the DTEEE, Brno University of Technology. The spectrometer enables us to experimentally verify the impact of various functional blocks on the detection abilities. Selected chemical substances containing chlorine and nitrogen isotopes were analyzed with the spectrometer.
