H-NMR studies were carried out for solution of amphiphilic betaine ester derivatives (of the general formula (CH)NCHCOOC HCl ( V-n), where n=10, 12, 14, and 16) and n-dodecyltrimethylammonium chloride ( I-12). The spectra were taken at concentrations above and below critical micelle concentrations and chemical shifts were analyzed. It was stated that micelles are hydrated at the depth of the two CH groups in the case of V-n and the CHCOO group in the case of I-12. Therefore, the CHCOO group during the micellization behaves as if it were CHCH group. [ABSTRACT FROM AUTHOR] |
