A team of researchers from the Institute of Physical and Mathematical Sciences and Information Technologies of Immanuel Kant Baltic Federal University (BFU), together with their colleagues from Gebze Technical University, used nuclear magnetic resonance to detect toxic and flammable nitrogen-containing liquids. The study was published in Chemical Physics.
Nuclear magnetic resonance (NMR) is the effect of energy absorption or emission by a substance that contains nuclei with nonzero spin in its external magnetic field. The set of resonance lines is individual for each substance and is used for identification. The stronger the magnetic field, the more information researchers can determine about substance structure. The most intensive NMR signals are observed in hydrogen nuclei.
