The Mid- and Near-Infrared Spectra of Water and Water Dimer Isolated in Solid Neon

The water dimer I: Experimental characterization

“…In rare gas matrices, water molecules rotate freely, whereas such rotation is hindered in a nitrogen matrix [5][6][7][8][9][10]. These rare gas studies indicated a bifurcated hydrogen bonded structure for the water dimer under the experimental conditions.…”

“…Subsequently, several other groups studied the mid-and nearinfrared spectra of water dimers in various cryogenic matrices [2][3][4][5][6][7][8]. Tursi et al [2] and Fredin et al [3], using a higher resolution spectrometer (1.5-1.0 cm −1 spectral slit width in the region of 3700-1150 cm −1 ), found four peaks in the O H stretching region of water and assigned them to a singly hydrogen bonded open dimer structure.…”

Matrix isolation spectroscopy of H2O, D2O, and HDO in solid parahydrogen

“…As might be expected, studies of trapped water monomers date back to the origins of the MIS field (35)(36)(37)(38)(39)(40)(41)(42)(43)(44)(45)(46)(47)(48)(49)(50)(51). Rovibrational spectra of water monomers in rare gas solids (RGS) are well explained by assuming that the water molecules exist as slightly hindered rotors in single substitutional vacancies (37)(38)(39)(40)(41)(48)(49)(50)(51), except for a few features assigned to "non-rotating"…”

The vibration–rotation of H2O and its complexation with CO2 in solid argon revisited

“…Before looking at the H 2 O:CO 2 complex, pure H 2 O in matrices had to be studied under our experimental conditions. Since the work of Glasel [12], all evidence indicates that H 2 O trapped in inert matrices, is almost freely rotating [13][14][15][16][17]. After some initial controversies, there is now general agreement on the assignment of the rovibrational absorptions in the n 2 and n 1 /n 3 regions in solid argon [16].…”
