The experimental results on the self-aggregation of fullerene C60 particles in a microvolume of drying droplets of a colloidal solution of fullerene on a solid substrate are presented. Using methods of scanning electron microscopy and atomic force microscopy, it was shown that in the volume of an evaporating droplet of a solution of fullerene C60 in xylene, deposited on the surface of a flat silicon substrate at room temperature, nanostructured and porous mC60 aggregates of quasispherical and elongated spherical shapes with geometrical sizes in average diameter up to D≈4000 nm are synthesized. It is established that an …

As a result of the experimental study of the spectra of anisotropic scattering of light, a character of orientation movement of molecules in aromatic hydrocarbons has been analyzed. The obtained results have been interpreted from the viewpoint of a model of inhibited rotation and the contributions of the rotational and vibrational degrees of freedom to a molecule spectrum have been estimated. With increasing temperature of liquids under study and approaching a critical state, the rotational degrees of freedom "freeze", and the vibrational degrees have become more significant.
