16. Several factors may be responsible for the experimental success rate of roughly 40% induced alignment. For example, if the amount of amphiphile formed on the surface of the water cell is insufficient, coverage is too low; if too much amphiphile formed, molecular reorientation is restricted. The length of time of solvent evaporation is also crucial, since it is during that window that the molecules self-assemble and align. Film transfer is also a delicate step during which the film may distort and the alignment is destroyed.
