Mnova incorporates an intuitive and powerful multiplet analyzer. The user will carry out an automatic multiplet analysis by clicking on its respective icon, placed on the analysis toolbar menu
, or by following the menu ‘Analysis/Multiplets Analysis/Automatic’.
Bear in mind that when you select an automatic multiplet analysis, Mnova will also apply in the background an automatic peak picking and integration, so you may need to set the ‘Noise Factor’ (and sensitivity) of the peak picking and the integration options to obtain good results.
If you select a ‘Manual Multiplet Analysis’, please check also the ‘Sensitivity’ and the ‘Noise Factor’ used for peak picking, or apply a ‘Manual Peak Picking’ to obtain a good result. You can also select the peaks by using the ‘Peak by Peak’ feature. Note that, by default, Mnova will find the peak top by using parabolic interpolation. To pick a peak at an arbitrary position (e.g. not at a local extreme or a shoulder), hold down <Shift> and click.
The user can also apply a manual integration followed by an automatic multiplet analysis (to obtain the same ranges in both cases), but please bear in mind that integrals and multiplets are two independent lists, so you will be able to have different ranges in both.
In the picture below, you will see the result of applying an automatic multiplet analysis:
Right clicking on the multiplet box and selecting ‘Report Multiplets’ will generate the Report of your multiplets. The same result will be obtained by selecting ‘Report’ in the ‘Multiplet Analysis’ scroll down menu (red rectangle in the picture below). Of course, the user will be able to add an icon for this feature (green square in the picture below) into the toolbar. See the tutorial ‘Toolbars Customization’ for further information about it.
The same result will be obtained by following the menu ‘View/Tables/Multiplets/Report Special’ icon:
The format of the Multiplet Report can be selected just by selecting ‘Setup’ (in the ‘Report Special’ scroll down menu). This will display the ‘Multiplet Report’ dialog box, which will allow the user to select the desired template (JACS, Royal Society of Chemistry, Angewandte or any other Custom Report).
