Abstract
In pure sodium deoxycholate (NaDC) dilute solution, the transverse relaxation times (T 2) of nearly all proton signals of NaDC obey single-exponential decay, with exception for proton at 3-position (H3) that decays in a two-exponential manner. The two components with different mobility of H3 of NaDC indicate that the molecules are probably associated in head-to-tail pairs via hydrogen bonds in dilute solution. In the mixed NaDC/cetyltrimethylammonium bromide (CTAB) solutions, the T 2 values of interested NaDC protons are far less than those in pure NaDC solution, especially when the concentrations of the two components are close to equal-molar. The results of self-diffusion coefficients and the chemical shifts confirm further that the strong interaction occurs between the two components in mixed solutions, especially for equal-molar condition. The arrangement of the mixed aggregates can be speculated for the cross-peaks of proton pairs occurring between NaDC and CTAB molecules in two-dimensional and rotating frame nuclear Overhauser enhancement spectroscopy spectra.
