The carried out polarization examinations of C10H8 spectrums of small frequencies of a Raman effect of light has revealed the presence of additional lines of small intensity. Calculation of histograms of spectrums of the lattice oscillations is carried out by Dyne's method. It is shown, that the presence of vacancies in structure of C10H8 leads to occurrence of additional lines around 90 cm-1. Occurrence of lines at frequencies less then 30 cm-1 is attributed to the presence of orientation disorder of molecules. Apparently, structure C10H8 has both types of defects, both orientation disorder of molecules and vacancies, which causes occurrence of additional lines in a spectrum of small frequencies.
