NMR Assignments

Assisted Assignments After entering the Manual Assisted Assignment mode, if you hover the mouse over the atoms of the molecule, the suggested multiplets in the spectrum get highlighted. When hovering the mouse over the multiplets, the suggested atoms in Compounds table get also highlighted. assignments 001 Capability to show 1H and 13C assignments in atom labels assignments 002 Assignments transferred to multiplets when copying an assigned molecule to a new dataset. Do not remove all correlations involved when deleting one of the shifts in case of ambiguous assignments. Remove all correlations involved when deleting an assigned multiplet, peak or integral. Remove all correlations involved when deleting the shift value of an assignment. H-H correlations between diastereotopic protons are auto deduced. 2D correlations auto deductions are checked again after replacing or swaping assignments. Remove all correlations involved when deleting an assigned multiplet, peak or integral. When assigning symmetric Hs all the attached Cs get auto deduced from the HSQC correlation. Second H of a diastereotopic CH2 auto deduced from the HSQC. Ability to add overlapping multiplets by assigning to a 2D range. Many pop up messages removed during manual assignment workflow. Improved auto deduction routines to get derived assignments from 2D correlations. Manual assignment propagation from 13C dimension of 1H-13C correlation transferred to 1H spectrum. Manual assignment propagation from 1H to 13C dimension now happens when 1H assignment is made on a 2D 1H-1H correlation spectrum. Improved transfer of manual assignment from 1H to 13C dimension when cross peaks are close on the 1H dimension of the 2D spectrum. Help messages in the status bar when using Assignment tool. Improvements in the report assignments script. Reports of assignments now switch to multiple columns when they are too long. Automatic recalculation of the 2D deductions after making some changes in the 2D spectra. In CH2 assignment if Ha is assigned show Hb label by default when assigning the second H.

Ability to delete assignments and correlations graphically from the spectrum.

delete_AssignCorr Report 13C peaks with multiplicity After making assignments to the 13C peaks the multiplicity gets automatically filled in Peaks table. This multiplicity information can be included in the Peaks Report by selecting it in Setup Report. assignments 003

Mnova NMRPredict

-“Best NMR” prediction has been implemented to enhance our NMRPredict module.

 

-Capability to select the default solvent reference in 19F and 15N NMR predictions.

NMR predict

-Capability to update predicted spectra in stacked plots.

Predicted spectra can be modified either graphically or by editing the values in Prediction table or Spin Simulation panel. Both spectra and tables get correctly updated after switching between the predicted spectra. In case of multiple predicted spectra in the stacked, the data displayed in the Prediction table and the Spin Simulation panel correspond to the active predicted spectrum. predicted stacked

– Ability to get highlighting like in Predict &Highlight using predictions read from a file via script.

– Capability to calculate 3J HNCH couplings.

Mnova MS

– Capability to load/save the Peak Detection options.

MS peak detection

The user can manually adjust the peak detection settings, allowing to specify the desired resolution to build the centroid spectrum. MS centroid

– Capability to load/save the Elemental Composition and Molecular Match settings.

MS elemental composition   MS mol match

– Align traces automatically depending on the LCMS machine.

This feature is useful to align UV/DAD and MS traces by using a correction value.   MS automatic Traces aligm Those parameters can be predefined from the ‘Edit/Preferences/Mass/Import’ menu: MS pref The trace alignment parameters are automatically applied to any new trace or DAD chromatogram and the default value for those parameters is determined by the selected preferences. When importing a dataset, if any of the rules matches, then the parameters present in the matched rule are copied to the new item. For the rules, you can specify to which provider (or any provider) the rule applies, and a set of parameter rules based on pattern matching: Ms rules

– Peak purity calculation.

This feature will calculate the chromatogram peak (or region) purity associated to the most abundant mass peaks which are displayed under the selected peak: Ms peak purity

 

– Improved vertical axis label for chromatograms.

Default checkbox has been added. When it’s checked, it means that the label will be set by Mnova to the default value for that kind of plot (so the label line editor remains disabled). If it’s unchecked, then the label will be set to whatever the user sets in the line editor. MS vert axis

– New converter Advion MS data.

Mnova NMR

– Denoising

In any experimental technique, the distinction between signals and noise is a real factor, and this is particularly the case with NMR because of its low inherent sensitivity. The application of the so-called ‘spatial filters’ has been proposed for the efficient denoising of images as well as for 2D NMR data sets. Mnova includes a number of those filters aimed at reducing the noise level while maintaining the original spectral resolution. denoising

– Zero Filling and LP dialog has been improved

zero filling

  1. The Zero Filling part of the dialog indicates from which point the zero filling starts in cases of:
    • Truncated FID,
    • The dimension f1 of phase-sensitive 2D spectra.
  1. The forward and backward LP are no longer shared, because:
    • The LP methods can be different.
    • Not all LP methods are supported in backward LP.
    • Base points and number of coefficients can also be different.
  2. If some LP parameters don’t match the sizes of the FID and spectrum then instead of auto-fitting them, a message box with the suggested corrections will appear as follows:
