Abstract
The smectic A to smectic C transition of a commercial ferroelectric m ixture (SCE13 and its racemic mixture) has been studied within a surfa ce stabilised cell using X-ray 'rocking curve' techniques. An unusual distribution of the layer orientation in the smectic A phase implies t he existence of a tilted structure. This phenomenon in the smectic A p hase is believed to be a result of an unusual temperature dependence o f the layer thickness and a comparison with a typical material is repo rted.
