Predicting the NMR spectrum for a chemical compound can c nmr predictor an important role in structure validation and elucidation. You can read more about the NMR chemical shift model description here. To get started with the NMR Predictor via cxcalc, use c nmr predictor. Atoms of the input molecule and multiplets c nmr predictor the NMR spectrum are linked together. Upon selection of an atom the corresponding multiplet is highlighted and vice versa.
A single NMR prediction is allowed to contain c nmr predictor molecules. You can predict both spectra of the molecule in question, which will appear in separate windows. Both NMR Prediction windows consist of a menu, toolbar, and four panels.
The name of the window is displayed at the top left corner. At the bottom left corner of the status bar general information on the NMR prediction is shown, i. The Edit menu can be used to copy specific panels to clipboard and to update the molecule from MarvinSketch.
You can also apply the right-click of c nmr predictor mouse on the proper panel to copy it to the clipboard. Options menu. The Options menu can be used to set optional NMR prediction settings: Change default setting to: It is to select different display options related to the predicted spectrum and the molecule structure: Default setting is on.
Active when reference spectrum is imported. Selecting individual multiplets. Using the Ctrl button while the cursor is located in this panel, the view of molecule can be controlled:. If you have added tautomers to the predicted spectrum via the Select Tautomers In the picture below symbols T1, T2, Hover over to see tautomer structure in a pop-up window.
Click on the symbol to make it active. The following tabs are c nmr predictor on this c nmr predictor Table on all tabs contains data dangi nrutya video er the predicted spectrum in Multiplet or Atom point of view. Coupling table contains the calculated coupling constants when the Spin-Spin coupling option is selected. Multiplet information table has six columns, namely: You can sort data according to these columns.
Atom number, Chemical shift, Net intensity, Multiplet information, and Quality. If you have added tautomers to the predicted spectrum via Select Tautomers The opened spectrum can be zoomed in, exported to PDF, or simply copy-pasted as an image.
The Spectrum View Panel displays the whole imported spectrum. The Spectrum Display Panel displays the appropriate zoom region of the spectrum. Right-clicking on any panel pops up a menu with the following element:.
