Dipolar-dephasing method provides some information about the strength of dipolar coupling in solids. Dipolar dephasing technique measures the time for a polarized carbon nucleus to lose its magnetization once the proton locking field is terminated. The dynamics of guest molecules adsorbed within the cavities and channels of nonporouszeolite strongly depend on the structure and chemical composit...

We have investigated the glassy behavior of a molecular crystal built up with chloroadamantane molecules. For a simple model of this molecule and a rigid fcc lattice a MD simulation was performed from which we obtained the dynamical orientational correlators Sλλ′(q, t) and the “self” correlators S λλ′(t), with λ = (l,m), λ ′ = (l,m). Our investigations are for the diagonal correlators λ = λ. Si...

Temperature dependence of Fano resonance, recently discovered in infra-red (IR spectra nanodiamonds synthesized from chloroadamantane at high static pressures, is investigated. For the first time, marked variations resonance parameteres are observed. On heating, shape changes considerably; effect completely disappears above 350 C, but recovered after cooling to ambient conditions. Such behaviou...

Globular molecules of 1-chloroadamantane form a plastic phase in which the molecules rotate in a restrained way, but with their centers of mass forming a crystalline ordered lattice. Plastic phases can be regarded as test cases for the study of disordered phases since, contrary to what happens in the liquid phase, there is a lack of stochastic translational degrees of freedom. When the temperat...
