    • The use of small amounts of trifluoroacetic acid (TFA) in the spreading solvent was necessary to dissolve monodisperse PBLG in chloroform, while the polydisperse PBLG dissolves in pure chloroform. The use of either pure chloroform or TFA-chloroform mixture as the spreading solvent for polydisperse PBLG samples did not have any noticeable effects on any of the measurements presented here. Since TFA is volatile, we expect most of it to evaporate from the monolayer surface after the spread-ing of the film, together with chloroform.

    • For example, Hickel et al. [Langmuir 6, 1403 (1990)] studied optical anisotropy in structurally ordered Langmuir Blodgett multilayer films formed by a different kind of α-helical polypeptide and found the refractive index parallel to molecular axes to be only about 1%-1.5% higher than the indices in the perpendicular directions.

    • note
    • If the orientational correlation length were long and the illuminated sample area viewed by the detector were not large enough to contain many randomly oriented domains, a full powder average would not be achieved. In such a case, the diffraction condition would depend on the orientation of the sample relative to the incident beam (as in the case of single crystals) and variations in peak intensity would be observed upon rotation about the surface normal.
