Abstract

High-resolution differential optical reflectivity was used to study the temperature evolution of the short helical pitch in the Sm-C * _α phase of successive members from two liquid-crystal homologous series. With the addition of one CH ₂ group, the magnitude and temperature evolution of the pitch change dramatically, and the molecular arrangements between consecutive surface layers found in free-standing films change from being anticlinic to synclmic.
