<title>Computer study of ethane absorption by ultra disperse water medium</title>

Abstract

Absorption of ethane molecules by monodisperse water system is investigated by the molecular dynamics method. Stability of (H₂O)₂₀ cluster characterizing a system is kept, while the number of captured C₂H₆ molecules will not exceed four. The capture of ethane molecules by disperse water system results in a decrease in both of the real and imaginary part of dielectric permittivity in the 0 ≤ ω ≤ 1000 cm ^-1 frequency range. The integral absorption coefficient of IR-radiation increases after absorption of C₂H₆ molecules by water clusters. The power of thermal radiation of water clusters absorbing ethane molecules decreases. Clusters absorbing two C₂H₆ molecules have the maximum power of radiation. This cluster has the greatest number of active electrons, interacting with a falling electromagnetic wave.
