Abstract: | Interaction of bromine ions absorbed by water cluster with adsorbed oxygen and ozone molecules has been investigated by the
molecular dynamics method. It was shown that the part of O2 molecules was removed from the system by evaporating Br− ions, while all O3 molecules and Br ions were kept in the system during 25 ps. The increase the concentration of the Br− ions in the clusters resulted in a reduction of the absorption intensity and emission in IR spectra at the presence of oxygen,
whereas the absorption intensity in the appropriate IR spectra of ozone-containing systems increased with the growth of a
number of the Br− ions. Raman spectra of oxygen-containing systems were poorly sensitive to the concentration of the Br− ions but the absorption intensity of Raman spectra for systems with ozone considerably decreased with the growth of a number
of bromine ions. |
