摘要：

A new model for the structure of surfactant monolayers at interfaces is proposed and its utility demonstrated by application to data from a recent neutron reflectometry experiment. From a least-squares fit of the model to the reflectivity of a C-14TAB monolayer adsorbed at the air-water interface, the polar tilt angle of the hydrocarbon chains is extracted as a fitting parameter. Implications for the nature of orientational ordering in adsorbed surfactant monolayers are noted and discussed.
