The search for new NQR frequencies is always a slow process, as the characteristic frequencies are scattered in a large frequency interval. The the search in molecular crystals can be made easier, as the frequencies are strongly related to the local environment around the atom, that is its functional group. In this contribution we have show that in fact there is a strong correlation between nitrogen frequencies and functional groups if the nitrogen is not embedded in the aromatic ring. This correlation can be therefore used to reduce the time required to find new frequencies, by searching only in specific areas.
B.03 Paper at an international scientific conference
COBISS.SI-ID: 26067495The memebrs of the project team are involved (via MPŠ) in the EU project CONPHIRMER, whose goal is the development of a portable NQR system for identification of pharmaceuticals at custom checkpoints.
F.06 Development of a new product
We have made several 14N NQR analysis of pharmaceutical substances for the slovene pharmaceutical company LEK. We have also agreed to continue the collaboration in 2013 with a contract.
