Torsional oscillation in liquid chlorobenzene at high molecular number densities
Abstract
Mori's statistical formalism is used to study the molecular dynamics and interactions of liquid chlorobenzene subjected to a kilobar range of pressure. Use of the formalism is only justifiable if the contribution made by induced dipole absorptions to the total f.i.r. band intensities are known and accounted for. The band shapes for the fast angular oscillations of the permanent dipoles alone are estimated using the calculated induced absorption in chlorobenzene at 1 bar, 295 K.
Using Mori's statistics it is found that the rotational freedom is small even at the lowest applied pressure and decreases further as the molecular number density increases.
