Box , Oulu, Finland E-mail: par. The porous solid formed from organic CC3 cage molecules has exceptional performance for rare gas separation. NMR spectroscopy provides a way to reveal the dynamical details by using experimental relaxation and diffusion measurements. Here, we investigated T 1 and T 2 relaxation as well as diffusion of Xe and SF 6 gases in the CC3- R molecular crystal at various temperatures and magnetic field strengths. Advanced relaxation modelling made it possible to extract various important dynamical parameters for gases in CC3- R , such as exchange rates, activation energies and mobility rates of xenon, occupancies of the cavities, rotational correlational times, effective relaxation rates, and diffusion coefficients of SF 6.

NMR Methods for the Investigation of Structure and Transport

In gas phase, collisions that affect the rotational angular momentum lead to the return of the magnetization to its equilibrium relaxation in Nuclear Magnetic Resonance NMR. We report R 1 in gas phase in a field of Our results allow one to test theoretical predictions of the intermolecular potential of water in gas phase. Water is the most extensively studied molecule on Earth. A precise determination of its intermolecular potential would allow accurate predictions of its properties in gas, liquid and solid phase. However, despite huge theoretical efforts 1 , 2 , a full agreement with experiments 3 , 4 , 5 , 6 has not yet been achieved.

The chemical shift anisotropy «(j (j,) of the S-F bond in SF 6 is found to be ± 50 ppm. The sensitivity of line shape to rf field level in the cubic phase between​.

 Она хотела его продать. - Не волнуйся, приятель, ей это не удалось. У тебя скверный вкус на ювелирные побрякушки.

 - Их мы можем проигнорировать. Уран природный элемент, плутоний - искусственный. Для урана используется ружейный детонатор, для плутония нужен взрыв. Это не числа, такие различия нас не касаются.
