Relationship Between Microscopic and Macroscopic Order Parameters

Relationship Between Microscopic and Macroscopic Order Parameters [Pg.75]

The diamagnetic susceptibility of a single rod-like molecule can be described by two parameters and representing the molecular response to a magnetic field applied parallel and perpendicular to the molecular axis, respectively. In tensor notation the magnetic susceptibility of the molecule is given by [Pg.75]

From the general formalism for rotation of second rank tensors it can be shown that [Pg.76]

But N (C — l) is simply the macroscopic diamagnetic anistropy of the perfectly ordered nematic phase, i.e.. [Pg.76]
