✦ Synopsis

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.

## Abstract The ^1^H NMR spectrum of chlorpromazine hydrochloride was fully assigned at 400 MHz. Similarly, the ^13^C NMR spectrum was assigned unambiguously using two‐dimensional NMR. Measurements of chemical shift as a function of concentration in D~2~O showed appreciable changes of shift of both
