Spectral Characteristics of Water Clusters in the
Presence of Nitrogen Dioxide
A. E. Galashev and O. R. Rakhmanova
absorption of NO2 molecules by a water cluster containing 25
molecules was studied by molecular dynamics. The calculated dielectric
characteristics of a system of clusters (1 ≤ i ≤ 6) were compared with similar data for a
cluster system of pure water. The ability of the disperse water system that
trapped NO2 molecules to absorb IR radiation increased, and the rate
of the absorbed energy emission decreased. The Raman spectrum of the disperse
system that absorbed NO2 molecules changed most significantly in the
low-frequency range. The emission time of cluster-generated radiation was much
smaller than the lifetime of the clusters.
