New method for DOSY processing using a novel Bayesian approach with just one click. For further information please visit Carlos’ NMR blog:
New Covariance NMR module, supporting both Direct and Indirect methods. The Direct method is able to produce a 2D spectrum in which the resolution in both dimensions is determined by that resolution of the spectrum in the direct dimension. In indirect covariance NMR spectroscopy, the spectral resolution along both frequency axes is determined by the sampling along the evolution t1 time.
This method provides a very simple way of modeling the baseline by selecting a well-distributed set of points that fall on the baseline and then interpolating between those points to complete the model. There are 2 methods for the interpolation: Segments and Whittaker Smoother.
It is now possible to synthesize coupled spin systems by just introducing the corresponding parameters (chemical shift, coupling constants, spin, spectrometer frequency, etc.)
It is possible to create expansions with Mnova just by clicking on the corresponding icon of the toolbar (or by pressing the <E> key) and then holding down the left mouse button and dragging.
New modeless dialog boxes has been included in the Mnova GUI to facilitate the NMR analysis. You will be able to use any other tool (i.e. zooming) whilst you are applying the phase correction (or you are working with the integral or multiplet manager dialog box).
Mnova gives the user the choice between three auto-phasing algorithms for higher flexibility. Indeed you can select more than one algorithm at the same time and the algorithms will be applied consecutively.
A new robust algorithm for the 2D automatic phase correction has been implemented.
A new feature to divide integrals has been implemented.
It is possible to increase the height and the weight of the integral curves by dragging the mouse.
It is possible to Restore and to Set as Default the desired Spectrum Properties.
The Noise Factor is a kind of intensity threshold. The program will automatically calculate the noise value of the spectrum. This noise value is then multiplied by the noise factor. After running the peak picking algorithm, peaks smaller than the noise value multiplied by the noise factor will be rejected. The program shows this vertical threshold as two horizontal lines in the spectrum.
A new powerful algorithm for automatic integration based in the peak picking has been implemented in this new version of Mnova.
It is possible to copy&paste the spectral properties and the integral regions or peaks from one spectrum to another, just by pressing ‘Ctrl+C’ in the original spectrum and then following the menu ‘Edit/Paste Properties’ in the other spectrum (or spectra, if you have previously selected them in the page navigator)

It is possible to change the colors of overlaid 2D NMR spectra by just modifying the palette
We have included some improvements in the interface of the stacked spectra in order to enhance the quality of the reports.
The new algorithms (High, Normal and Low) are now easier to use.
It is now more comfortable to navigate through the integrals and multiplets from the corresponding manager dialog boxes (moving to the area of interest, if it is necessary).
The multiplet manager dialog box has been enhanced with several option. Bear in mind that you will be able to use any other tool (i.e. zooming) whilst you are in this dialog box.
This tool will be very useful to calculate the number of nuclides of a determined spectrum.
It is possible to reference integrals to the total integral value for the spectrum.
The prediction shows the assignments on tops of the peaks
It is possible to tie crosshair cursors together over multiple experiments
It is now possible to run X-nuclei predictions with NMRPredict Desktop.
NMR Predict Desktop also includes the calculation of heteronuclear (HF, HP, CF and CP) couplings.
It is now possible to introduce new coupling constants from the prediction table.
The layout template feature has been enhanced and now it is possible to import templates from a .mnova document. The new layout templates will keep all the properties of the objects, the processing and the analysis features used in the original spectrum.
Now it is possible to apply a created layout template to a spectrum (or spectra) just by following the menu View/Layout Templates/Apply template document
The new table shows the molecules present in the document with information about the chemical formula and molecular weight.
The new availability of scripting in Mnova provides opportunities and benefits both for skilled NMR and casual, non-expect users.
It is possible to import spectra as 1D ASCII files.
It is possible to help to the ASCII converter to import user specific ASCII files by modifying some script functions. This mechanism is so powerful that it is possible to import not only ASCII but any kind of files in user specific format.
You can edit the title of the spectrum shown in the page navigator just by right clicking on it and selecting “Edit Page Title”.
