Induced dipole moments of H 2O and NO 2 molecules diminish during the addition of one to six NO 2 molecules to (H 2O) 50 cluster. The integral intensity of IR absorption by a system consisting of (NO 2) i(H 2O) 50 heteroclusters with 1 ≤ i ≤ 6 decreases, whereas the power of heat emission rises as compared with an (H 2O) n system. The decrease in the IR absorption and the increase in the IR emission by water clusters with the capture of NO 2 molecules are nonmonotonic. The absorption of NO 2 molecules by water clusters causes a noticeable reduction in the intensity of the first peak and the confluence of the fourth and fifth peaks in the Raman spectrum |
