  We measured the small frequencies Raman spectrum of the paradihlorobenzene
and paradihlorobenzene solid solution nanoparticles with the size about 100
nanometers. Values of frequencies of lines decrease. The size of nanoparticles
was determined by the electronic microscope. Calculations of nanoparticles
structure were done using the method of molecular dynamics and histograms of
nanoparticles spectra were calculated via the Dyne's method. The result is that
the Raman spectrum is the sum of spectra from the central part of the
nanoparticle and superficial structures with smaller concentration of
paradihlorobenzene.
