10. High field states are not usually seen in free-standing films because a large field usually induces flow.

13. Although the compound had degraded, we do not expect the optical properties to change dramatically from the undegraded state. From our x-ray studies we know that the layer spacing does not change much as a function of temperature in the (Formula presented) phase.

17. In our previous papers our (Formula presented) values are incorrectly offset by (Formula presented) from their correct values. This does not affect the values of any other physical parameters.

24. Two other effects made determination of N difficult for thicker films in the (Formula presented) phase in the DRLM setup. The laser used for reflectivity was not intensity stabilized, and the biaxiality of the phase made the reflected light intensity a function of alignment of the probed domain.
25. Our sample of 8OF (Formula presented) was used up so a more exhaustive study of this compound could not be done.
26. The large error in (Formula presented) may be due to (Formula presented) or d changing with N.
27. NTE is insensitive to (Formula presented) rotations in molecules about any of their principal axes because the ellipsoid of refraction remains unchanged upon such an operation. Therefore the orientation of (Formula presented) must be inferred from the polarization direction.
28. The results for the films of even N are often those of more than one domain. This was unavoidable because of the large amount of time required to allow the domains to reorient on their own.
