Studies on microstructure of dodecylbetaine system with H-1 NMR and Raman method

H-1 NMR spectroscopy was used to study the microstructure of dodecylbetaine /phenylcarbinol/water system and determine the position of phenylcarbinol m olecule in the micell. It was found that there was another kind of transiti onal structure beside W/O and O/W type in the system. According to the resu lts of 1H NMR and Raman study it should be a long-range ordered structure c alled pseudo liquid crystal. Analyzing the H-1 NMR spectra of the system th e range of the three types of micell was given: W/O, pseudo liquid crystal, O/W. In pseudo liquid crystal system, the molecules were highly orderized.
