NMR Shift Information-ChemNMR

---

ChemNMR is a feature of ChemDraw Ultra only. ChemNMR estimates and displays proton and carbon-13 chemical shifts in ppm for a selected molecule.

To view ¹H or ¹³C NMR information:

1. Select the target chemical structure.

2. From the Structure menu, choose 1H-NMR Shifts or 13C-NMR Shifts.

ChemNMR redraws the molecule with the estimated shifts and displays the information and line spectrum in a new window as shown below.
