What's New in ACD/Spectrus Processor

Version 2021

Version 2021 of Spectrus Processor adds new features, including expanded data import from Shimadzu CDS, capabilities to work with rotamers and series data for NMR, and the ability to annotate mass spectra with fragment structures. We have also improved existing functions. Read below for details, and contact us for help upgrading your software.

Improved Data Import

New Features for NMR Data Processing

Define Co-existing Rotamers in NMR Spectra

Unfold Folded 2D Spectra to Get the True Position of Peaks

Apply process-correct aliased frequencies to adjust the spectrum along F1 range. After unfolding, the signals appear at their correct position around 220ppm (right)
Left: overlaid HMBC (red) and HSQC (green) spectra of azithromycin. The signals from HMBC appearing at ~0 ppm in 13C belong to folded peaks. Their true position is greater than the HMBC upper F1 range. Apply process-correct aliased frequencies to adjust the spectrum along F1 range. After unfolding, the signals appear at their correct position around 220ppm (right).

New Features for MS & Chrom Data Processing

Display Fragment Structures as Peak Annotations

Record and Automate Frequent Actions

Improved Features

Integrate All Peaks in Series of NMR Data

Display and selectively position the integral values for all peaks in a 1D 1H NMR series in group mode.
A series of 1D 1H NMR spectra for ethylindanone. In group mode, you can display and selectively position the integral values for all peaks in the series.

Access More Features by Converting Flat Chromatograms into Hyphenated Data

Improve Processing with More Tools and Options

Refinements in Database Search Capabilities

Improved search for structures that include graphical objects, molecules with chiral centers, and data range values
