Abstract
The p-nitrobenzoate ion and its conjugale acid have been oriented in both cationic and anionic detergent based lyomesophases. In the cationic phase there is no marked change in the order of the C2 axis as the hydrogen ion concentration of the water region of the phase is varied. The degree of order along the C2 axis is decreased considerably in passing to the anionic detergent based phase and in this phase the degree of order of the ion does increase in the expected manner on protonation. The orientation of the larger organic counter ion and its acid is probably complicated by insertion into the hydrophobic region and use of the —NO2, —CO2−, or —COOH moieties as head groups.Keywords
