Next, go to the Structure menu and select "Predict 1H-NMR Shifts" or "Predict 13C-NMR Shifts." ChemNMR redraws the molecule with the estimated shifts and displays the information and line spectrum in a new window.įigure 1: Selecting an NMR prediction in ChemDraw To view 1H-NMR and 13C-NMR predictions, select the target chemical structure. At the end of this article are links to webinars and other articles about each of the computational chemistry packages that Chem3D interfaces with.ĬhemDraw's ChemNMR package is fully integrated with ChemDraw - a user draws a molecule and the NMR spectra can be viewed with one click. Other computational chemistry packages, such as MOPAC, can be integrated into Chem3D (several others are also included) - if others develop NMR or IR spectra predictions, PerkinElmer will include them in future versions of this article. One such computational chemistry package, GAMESS, is integrated into Chem3D and included in its purchase price. Some computational chemistry packages include NMR predictions and some include IR predictions as part of their computational software.
