| Abstract: | We perform a molecular dynamic study of collective excitations of carbon tetrachloride and compare the results with the experimental data from the literature. The data of simulations are in good agreement with the experimental ones. The results of the simulations confirm the presence of large positive sound dispersion (PSD) in carbon tetrachloride, which should be related to some relaxation processes which do not take place in atomic systems. • Molecular dynamics simulation of the excitation spectra of CCl 4 is performed. • The results are in agreement with the recent experimental data. • Large PSD is induced by long-lived processes indicated by VACF.
