Computer Simulation of the Absorption of CO2 Molecules by Water Cluster: 3. Dynamic and Dielectric Properties

Autocorrelation functions of translational and angular velocities of H 2 O and CO 2 molecules in (CO 2 ) i (H 2 O) 10 clusters that are generated by the molecular dynamics method, as well as their frequency spectra, are calculated. Self-diffusion coefficients of molecules in clusters are determined. The IR spectra thus obtained and frequency-dependent dielectric permittivity of the clusters indicate the enhancement of absorption of Earth' thermal radiation by these aggregates with an increase in the number of CO 2 molecules in the aggregates. Dielectric losses also increase with the i number.
