Abstract 1 H and 13 C NMR assignments of sodium chenodeoxycholate in aqueous solution were obtained for three different bile salt concentrations. 1 H and 13 C NMR chemical shifts of sodium chenodeoxycholate and deoxycholate show slight concentration dependence due to micelle formation. Opposite trends in chemical shifts changes for α‐ and β‐protons cause polarization of the steroid nucleus.
