Nonharmonic libration

B. Nonharmonic Libration of a Permanent Dipole in a Deep Well... [Pg.321]

The model comprises the librational (LIB) and vibrational (VIB) fractions. A rigid permanent dipole, constituting the first (LIB) fraction, performs nonharmonic reorientation in the part of the structure formed by weak or torn hydrogen bonds (HB). This fraction stipulates the librational band of ice located at 800 cm-1. The second (VIB) fraction, constituted by two elastically vibrating oppositely charged HB molecules, describes T- and V-bands, located in... [Pg.394]

The librational (LIB) fraction is attributed to an individual neutral polar H20 or D20 molecule (monomer), reorienting nonharmonically in tight surrounding of water medium. The molecule is represented as a rigid dipole... [Pg.429]
