Spectrus: Handling overlapping multiplets in crowded regions of NMR spectrum
DescriptionIn crowded spectral regions, multiple multiplets can overlap, making it difficult to assign peaks and obtain accurate integrals. Spectrus provides tools to zoom, deconvolute, and manuall...

Spectrus: Exporting NMR peak tables and assignments to TXT or JSON
DescriptionUsers often need NMR peak positions, integrals, and assignments in a spreadsheet for external processing or reporting. Spectrus can export these data tables directly to text or JSON form...

Spectrus: Reassigning NMR peaks after structure changes in Spectrus
DescriptionIf a structure is modified after NMR assignments have been created (for example, adding/removing atoms, changing numbering), existing assignments may no longer match correctly. Spectrus ...

Spectrus: Handling solvent peaks and reference signals in NMR spectrum
DescriptionSolvent peaks and reference compounds (e.g., TMS, residual solvent signals) are often present in NMR spectra. Properly identifying and, where needed, excluding these peaks is important f...

Spectrus: Organizing multi‑technique data (LC/MS, NMR, UV) in one Spectrus project
DescriptionA typical workflow involves combining multiple analytical techniques (LC/MS, NMR, UV/Vis, etc.) for a single sample or set of samples. Spectrus allows organizing these data together in o...

Spectrus: Understanding “Intensity” vs “Integral” values for NMR data in Spectrus
DescriptionIn NMR, intensity and integral represent different numerical measures:Intensity is the height of a peak at a specific frequency point (amplitude of the signal).Integral is the area under...

Spectrus: Exporting LC/MS chromatograms and spectra for use in other tools
DescriptionUsers may need to export LC/MS chromatograms or mass spectra from Spectrus for processing or reporting in external software. The export should preserve key information such as retention ...

Spectrus: Restoring default toolbar and layout settings
DescriptionAfter extensive customization of toolbars and windows, Spectrus may appear cluttered or certain tools may be hidden. Users may want to reset the interface back to the factory default lay...

Spectrus: Disabling automatic phase correction for imported NMR spectra
DescriptionBy default, NMR data imported into Spectrus Processor may be automatically phase‑corrected. In some workflows (for example, method development or teaching), users may prefer to load spec...

Spectrus: How to clear previous annotation suggestions
DescriptionSpectrus modules maintain a history of text used in annotation dialogs (for LC/MS, NMR, UV/IR, etc.). There is no in‑application option to clear this list. The history is stored in the W...
