Abstract —The molecular dynamics method is used to study the adsorption of ammonia on water clusters. The adsorption of ammonia is accompanied by a decrease in the ability of the cluster system to absorb infrared radiation, a significant decline in the thermal radiation power emitted by the system, and an almost double decrease in the frequency-averaged reflection coefficient. An increase in the concentration of ammonia in the clusters causes a slight change in IR absorption coefficient, but enhances the power of emission and reflection coefficient.
