Then hover the mouse over the multiplet box A, click and drag to the the label (B) of the peak 3, or vice versa, hover the mouse over the label of the peak 3, click and drag it to the multiplet box A (as it is shown in the picture below):Īfter that, the peak 3 will be a part of the multiplet A (at this moment the multiplet A contains the peaks 1, 2 and 3):įinally, do the same procedure with the peak 2 and the multiplet box B (click and drag the peak label to the multiplet box or vice versa), in order to include the peak 2 into the multiplet B:Īs you can see in the picture above the multiplet A contains the peaks 1 and 3 and the multiplet B contains the peaks 2 and 4.

This will add a peak label with the multiplet name (A and B) over each peak, as you can see below: For the NMR data analysis, MestReNova software (version 10.0. With this tool you can also remove peaks from the multiplet, by picking over a previously picked peak. Abbreviations for data quoted are m, multiplet s, singlet dd, doublet of doublets d. Once there, click on the 'Add multiplet peak' button (red square in the picture below). Next, double click on any of the multiplet boxes to launch the 'Multiplet Manager' dialog box.

First of all, divide the multiplet just by clicking on the red square of the multiplet label (to obtain two overlapped multiplets): Where the peaks 1 and 3 correspond to one doublet and the other peaks (2 and 4) to the second doublet. Mnova Lite Special Edition is a stripped-down version of Mnova software. Different specific software for NMR, such as TopSpin (Bruker), MNova. Supports the following instruments protocols, does multiplet assessment.

It is really easy to resolve overlapped multiplets. The multiplet structure (the relative positions and intensities of the lines). Abbreviations used: q-NMR, quantitative nuclear magnetic resonance LOD, limit of detection PULCON, pulse length-based concentration determination CPMG.
