Edited Sum integration method. A new integration method, "Edited Sum" has been implemented, where the values from Sum method are corrected using a correction factor: Sum(Ps_i)/Sum(P_i). "Ps_i" are the selected peaks (by default, including Compound peaks and excluding Hidden, C13_Sat and Rotational); "P_i" are all peaks in the integration range.   Int (Edited Sum) = Int (Sum)* (Sum(Ps_i)/Sum(P_i))   Data Analysis for Time-Domain studies This feature will be used for the processing and analysis of low-field, time domain data acquired in Oxford Instruments.

Capability to display spectra by peak type. It will be possible to display the spectra with 'All Peaks' (default view), only with 'compound peaks', only with 'solvent+impurity' peaks and also to generate a stack plot with the different views.

Here you can find an example of the stacked sub-spectra view obtained from a 1H-NMR spectrum:

Ability to show the indirect FID after having applied a LP (e.g.) in t1. Currently you can display the processed fid before the second FT (in t1), under the option "Spectrum after 1st FT Processed".

Frequency shift in f1 and f2. Frequency shift in f1 and f2 is possible by following the “Processing/Frequency Shift” menu. When applying for example 100 Hz in f2 or f1, a shift isapplied in f2 or f1 dimension, respectively:

Handling of coupling constants in the table of assignments. It will be possible to include coupling constants in the assignment table just by typing the value of the coupling followed by the atom number involved. If you want to add an ambiguous assignment, just type the coupling constant value and press the 'enter key' (a question mark will be added between brackets)

The couplings will be added by pairs, in the same way as in the correlations columns, i.e., when the J(2-3) is created, the coupling J(3-2) is also automatically added, with the same value. The table will give priority to the homonuclear couplings. Thus, when the user writes in a H row the atom number (without specify a proton), the coupling will be done between the protons. To add a coupling H-C, the user will have to write the atom symbol, for example, "C". The same for the cases in which the user writes in a C row, the coupling will be done between the carbons, by default. In the case of CH2 with no equivalent protons: the user should type the correct proton notation in the coupling. If we want to add a coupling with the first proton of 13CH2, and the notation is cis/trans, the text should be "1.20(13cis)". If we type "1.20(13')", we will get a message saying "the atom 13' doesn't exist in the molecule".

Importing J couplings from SDfiles Improvements in PCA. Ability to export the tables as CSV. Normalization step has to be introduced into the main PCA menu. New option to change the color of the spectrum based on the value of the loading value.

Enhancements in zoom cursor. The zoom cursor shows information about the position (same units as in spectrum scales). Once the starting position is selected, only the values for the ending position (f1, f2 or both dimensions, depending on the type of the zoom applied) are displayed.

This new feature can be toggled from the preferences.

Improvements in crosshairs and Info View. When activating the crosshair tool, the Cursor Info panel gets displayed automaticaly.

• in any other mode (like manual peak picking, integration, multiplet analysis, zoom, reference, assignment...) the information about the cursor position of the cursor is appearing attached to the cursor. If the Cursor Info panel is displayed, the information is also shown there.
• A button to copy the info from Cursor Info panel was added.
• in a page with multiple spectra, it is not necessary to select one spectrum to make the crosshair work.

Small Improvements in SpinSimulation. The simulated spectra are generated by default with 64K spectral size and -2 to 14 ppm range. Avoid duplicated labels in a Simulation when editing the group labels. Show transitions like GSD peaks instead of sticks in the simulated spectra.

Use filename as title in Oxford Instruments files Export to JCAMP-DX only the real part of spectra.

Bugs fixed

• Peak selection had problems on solvents.
• Multiplet integrals were always calculated using Peaks method.
• Problems moving peaks when a predicted spectrum was stacked to another page.
• Problems highlighting a simulated spectrum.
• Probems with absolute reference.
• Problems displaying DOSY peaks in Peaks Table.
• Hide NUS option for normal 2D spectra.
• Apodization function should adapt to the usage of forward linear prediction.
• Wrong highlighting on the transitions in the stacked spectra.
• Varian HSQC not processed correctly - Apodization functions were not right.
• NOESY showed noisy.
• Wrong couplings when the atom number was changed.
• Assignments Table: problems in the coupling columns delegate.
• Not possible to show the assignments of one of the molecules (after having edited the copy of the original molecule).
• Adjust apodization function to the desired linear predicted points.
