✦ Synopsis

IR relative integrated intensities and half-widths of rocking (R) and wagging (W) bands of water in M&la-2HaO

and CoCla-2H20 are presented at 300 K and 120 K. Departure of observed intensity ratio ~!DR from those predicted by the fixed dipole model is attributed to anisotropic dynamic changes in dipole moment during these oscillations. A quantity representing the variation of this anisotropy between Wand R oscillations is computed and its origin is discussed. An increase by 20% to 50% in both DW and DR on lowering the temperature has also been discussed.
