  An infrared study of the stretching modes of the water molecules in ZnF2·4H2O

  摘要：

  The IR spectra of ZnF2.4H2O and its deuterated analogues are reported at ambient and liquid-nitrogen temperatures. The O-H and O-D stretching and bending vibrations of the water molecules are analysed in detail. The two types of water molecules give rise to different absorption peaks in the O-H and O-D stretching regions in samples that contain isotopically dilute HDO groups. The strongly hydrogen-bonded water molecules H2O(1) and H2O(4) show four broad O-H and O-D stretching modes at lower frequencies, while the weaker hydrogen-bonded ones H2O(2) and H2O(3) give rise to four narrow bands at higher frequencies. The nu(OD) frequencies of isotopically dilute HDO groups correlate very well with the known R(H---F) and R(H---O) distances in the crystals and the assignment of these modes was done on this basis. It was also found that the ratio nu(OH)/nu(OD) decreases with decreasing values of R(H---O) or R(H---F) in ZnF2.4H2O.
