Study of a Conformational Equilibrium of Lisinopril by HPLC, NMR, and DFT

Figure 6

NOE difference spectra of lisinopril in D2O/CD3CN (9/1, v/v), at 298 K and 300 MHz. Irradiation of H43 and H48 (a, c) major conformer; (b, d) minor conformer. The numbers next to the peaks represent the quantified NOE at H58.
