Orientation Studies of Probe Molecules in Lamellar Liquid Crystalline Lipid Systems by Linear Dichroism

Artikel i vetenskaplig tidskrift, 1977

The LD-method of inclined incidence was found useful in the study of the orientations of probe chromophores (carotene, anthracene) solubilized in lamellar mesophases of the systems sodium octanoate/decanol/water and sodium di-2-ethylhexylsulphosuccinate/water, respectively. The results suggest the existence of two competing molecular orientation mechanisms aligning the longest axis of the probe molecule either parallel with the lamellar surface or perpendicular to it.
