标题: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.
