Abstract—Spectral characteristics of (H2O)i, N2(H2O)i, and(N2)2(H2O)i, cluster systems, where 10≤i≤50, are studied in the 0≤ ω≤ 3500 cm1 frequency range with the molecular dynamics method on the basis of a flexible
molecule model. After nitrogen is captured by an aqueous disperse system, the absorption of the IR radiation
by this system increases owing to the enhancement of intramolecular vibrations. In general, the reflection of the
outer IR radiation by nitrated aqueous disperse systems is attenuated; however, when the nitrogen concentration
increases twofold, there is a tendency toward an increase in the fraction of reflected radiation. As the nitrogen
concentration in a system of water clusters rises, the power of radiation emitted by the system increases significantly and the number of electrons interacting with the outer IR radiation decreases.
