“…Most of the observed lines inFig. 1͑a͒are assigned to the H 2 O monomer; the relative intensities between the monomer lines agree with those reported at 20 and 30 K 12,13. In addition, the five features of the H 2 O dimer at 3707.5, 3573.6, 3632.9, 1611.0, and 1593.2 cm −1 are observed, which correspond to the free and bonded OH stretches of the PD, the 1 stretch of the PA, and 2 bends of the PD and PA, respectively.…”

“…3,[5][6][7][8][9][10][11][12][13] For the H 2 O dimer, four absorption lines corresponding to the OH stretching vibrations were assigned in the previous studies 9-12 to the 1 symmetric and 3 asymmetric stretches of the PA and PD molecules. The two OH stretching modes of the PD molecules, however, should be denoted as the "free" and "bonded" OH stretches.…”

The infrared spectra of the water-nitrogen complexes trapped in argon matrices have been studied with Fourier transform infrared absorption spectroscopy. The absorption lines of the H20-N2 1:1, 1:2, 1:n, and 2:1 complexes have been confirmed on the basis of the concentration effects. In addition, we have observed a few lines and propose the assignments for the 2:2, 2:3, and 2:4 complexes in the nu1 symmetric stretching and nu2 bending regions of the proton-acceptor molecule, and in the bonded OH stretching region of the proton-donor molecule. The redshifts in the bonded OH stretching mode and blueshifts in the OH bending mode suggest that the hydrogen bonds in the (H2O)2-(N2)n complexes with n = 1-4 are strengthened by the cooperative effects compared to the pure H2O dimer. Two absorption bands due to the 3:n complexes are also observed near the bonded OH stretching region of the H2O trimer.

“…In Ar matrices, the rovibrational lines of the H 2 O monomer have been well characterized in recent studies, 11,12 and the bonded OH stretching bands of the water clusters have been identified in our previous study. 13 The observed spectra in the OH stretching region are displayed in Fig.…”

The infrared spectra of the (H(2)O)n-SO(2) complexes trapped in argon matrices have been investigated using Fourier transform infrared spectroscopy. In addition to the 1:1 and 2:1 complexes, the first spectroscopic evidence for the 3:1 complex has been obtained from the spectra of the SO stretching and the OH stretching modes. The observed frequency shifts in the bonded OH stretching region indicate that the hydrogen bonds of the 2:1 and 3:1 complexes are strengthened compared to that of the 1:1 complex, which suggests the cyclic structure of the complexes.

“…3(a), which means that nr monomers are difficult to diffuse and contribute little to the cluster growth. If we assume that rotation of a water molecule is suppressed just because of the dipole-dipole interaction with another monomer located close, 32 the column density of the nr monomer should be changed by heating procedures owing to the monomer diffusion. However, this contradicts our experimental result of the constant nr-monomer intensity.…”

D2O clusters isolated in rare-gas solids: Dependence of infrared spectrum on concentration, deposition rate, heating temperature, and matrix material

The infrared absorption spectra of D2O monomers and clusters isolated in rare-gas matrices were systematically reinvestigated under the control of the following factors: the D2O concentration, deposition rate, heating temperature, and rare-gas species. We clearly show that the cluster-size distribution is dependent on not only the D2O concentration but also the deposition rate of a sample; as the rate got higher, smaller clusters were preferentially formed. Under the heating procedures at different temperatures, the cluster-size growth was successfully observed. Since the monomer diffusion was not enough to balance the changes in the column densities of the clusters, the dimer diffusion was likely to contribute the cluster growth. The frequencies of the bonded-OD stretches of (D2O)k with k = 2-6 were almost linearly correlated with the square root of the critical temperature of the matrix material. Additional absorption peaks of (D2O)2 and (D2O)3 in a Xe matrix were assigned to the species trapped in tight accommodation sites.
