Applications:

  1. Studies of molecular dynamics in solids by deuteron NMR spectroscopy and relaxation in a wide temperature range (4.2 - 300 K)
  2. Structural studies of a wide range of new materials by high resolution solid state NMR spectroscopy, using MAS technique. The spectra of the following nuclei are most often studied: 29Si, 27Al, 23Na, 9Be, 11B, 79Ga, 51V i 31P.
