“…Common structures include micellar solutions, hexagonal, bicontinuous cubic, and lamellar structures. Molecular conformation in surfactant solutions has been shown to be strongly dependent on concentration, , largely due to the influence of self-assembled structure. A study of the conformational properties of different phases helps us to understand their structure more thoroughly at a molecular level.…”

A study using both Raman spectroscopy and molecular dynamics (MD) simulations was carried out for alkyl ethoxysulfate (AES) surfactants at various concentrations in solution. Direct comparison between experiment and simulation shows that the conformational changes observed in MD are in good agreement with those obtained via Raman spectroscopy. We show that there is an increase in the relative number of trans conformations with increasing concentration and illustrate the relationship between phase structure and molecular conformation, which is often speculated but difficult to confirm. Our results open up the possibility of applying MD to other surfactants, with the aim of analyzing conformational behavior, which can typically be difficult to study experimentally using spectroscopy methods, due to large numbers of vibrational modes present in large complex molecules.
