Abstract—The molecular dynamics method was used to calculate the frequency dependences of the dielectric constant for water clusters and the IR absorption spectra of water clusters containing from 5 to 90 molecules. The frequency dependences of the phase difference between the electric displacement (D) and electric field strength (E) vectors and the dielectric loss spectra for clusters were determined. The dependences of the maximum value of the coefficient of absorption of IR radiation by clusters and the frequency at which it occurs on the cluster size were determined.
