Magnetic resonance spectroscopy group

Keywords: NMR of advanced materials in solid and liquid states; CW-FT EPR spectroscopy

Group members are experts in  NMR spectroscopy of solids and liquids and EPR spectroscopy.

Research group activities

  • Crystallographic aspects, spin diffusion and spin-clusters size profile determination in nano-structured complex solids applying CP-MAS technique;
  • Structure elucidation of organic compounds applying high resolution 1D/2D NMR techniques;
  • Molecular-ionic processes in ionic liquids and composites forming liquid crystalline iono-gel mesophases;
  • Large-amplitude proton dynamics in hydrogen bonded systems;
  • EPR Studies of defects induced by (I) impurities; (II) by ionizing radiation: (III) free radicals in bio-systems.



NMR spectroscopy of solids and liquids:

Magic angle spinning (up to 15 kHz) experiments for solid state NMR with 400 MHz wide bore magnets. The probe possesses an X channel which is tunable from 15N to 31P. Wide line NMR experiments – starting from polymers to single crystal studies and metal physics in frequency range 109Ag – 31P; Variable temperature range –150°C to +400°C; Static low temperature wide line NMR applications for 109Ag – 31P; Variable temperature range from room temperature to > 8K.

EPR spectroscopy:

CW regime: sensitivity: weak pitch international standard 2500:1; absolute 1.2 x 109 spins / G; up to 80 MHz tuning range; FT regime: sensitivity: with 10 μM TEMPOL in toluene in 10 sec 200:1; 2 ns time pulse resolution. Helium Temperature Control System (3.8 - 300 K); Variable Nitrogen Temperature Control System (Temperature range 100 K - 500 K); Programmable one axis goniometer, 1/8 degree resolution.
