Sukurta: 27 November 2018
Unit: Faculty of Physics
Keywords: NMR, nuclear magnetic resonance, spectrometry, CP/MAS experiments, EPR, electron paramagnetic resonance

Application. Studies of organic molecular structure. Study of metastable defects in crystals. Identification of technological point defects and investigation of evolutionary heat treatments. Studies of Spin-labeled compounds, important in biomedical physics. Monitoring of free radicals and radioactive contamination.

NMR spectrometry of solids and liquids:
CP/MAS experiments:
Readjustment range - from 15N to 31P and 1H, a frequency of 15 kHz can be reached;
Temperature adjustment range from –140°C to +150 °C;
Broad band NMR registration:
Readjustment range - from 109Ag to 31P, temperature adjustment range from –150 °C to +400 °C;
NMR registration of very low temperatures:
Readjustment range - from 109Ag to 31P, temperature adjustment range from room temperature to 8 K;
Research of high resolution NMR spectra of liquid samples.
Adjustable temperature range: from –150°C to +150°C.
EPR studies:
Temperature control ranges:
100 K - 500 K, using liquid nitrogen and 3,8K - 300K, using liquid helium.
Programmable goniometer of 1/8 degree resolution.
