Application of nuclear
quadrupole resonance (NQR) spectroscopy in studies of:
- electronic structure of molecules and molecular systems;
- electronic effects (inductive,conjugative) in these systems;
- crystal structure and its defects;
- molecular dynamics (mainly librations and hindered rotations);
- phase transitions.
These studies are carried out
on the following materials:
- biologically active substances like anticancerous drugs,
antibiotics, bacteriostatic drugs, anesthetics, drugs reducing
hypertension, dermal penetration enhancers, disinfectants and
pesticides (insecticides, herbicides). The studies of these substances
have been undertaken to find a correlation between the electronic
structure of the molecules and their biological activity;
- other compounds of wide application like new semiconductors,
explosive materials;
- new compounds revealing interesting properties, having
interesting structure or interesting molecular dynamics.
In addition to the NQR spectroscopy, the fundamental research method employed
in the Division, the following supplementary methods are used:
- NMR and EPR spectroscopy,
- X-ray fluorescence spectroscopy,
- Thermal analysis methods,
- Quantum-chemical calculations.
Moreover, the staff is involved in:
- development of the theory of NQR phenomenon;
- development of a new measuring techniques aiming at shortening
the time of measurement, improvement of the sensitivity and resolution
of NQR spectra;
- construction of an NQR and double resonance NMR-NQR spectrometers
with enhanced technical parameters;
- design and construction of the devices based on NQR phenomenon
for detection of explosives and narcotics in luggages and for
detection of non-metallic mines.
RESEARCH PROJECTS REALIZED RECENTLY
1.
For army, police and customs
services (1994 - 1997):
"Design and construction of prototype device for remote detection of
explosives and narcotics in luggage by the nuclear quadrupole resonance
method".
2.
For army (1999 - 2003):
"Design and construction of a prototype device for the detection of
non-metallic landmines based on nuclear quadrupole resonance
phenomenon".
The devices have been constructed in our Division and
successfully passed all the tests under the supervision of army.
