Type of rotational motion in terms of the quasielastic spectra and the elastic incoherent structures factor for the aromatic groups.

    Solutions of fullerene C60 in toluene and p-xylene were investigated by small-angle X-ray diffraction. In all small-angle scattering curves, the scattering intensity decreases to constant value IC with an increase in the scattering angle. The value of IC nonmonotonically depends on the fullerene...

    NH4(C6H5)4B represents a prototypical system for understanding aromatic H bonds. In NH4(C6H5)4B an ammonium cation is trapped in an aromatic cage of four phenyl rings and each phenyl ring serves as a hydrogen bond acceptor for the ammonium ion as donor. Here the dynamical properties of the...
