ACD/Labs 11 includes updates to desktop NMR, mass spectrometry and optical spectroscopy products, as well as those for chemical nomenclature generation, chemical drawing, physicochemical property prediction and chromatography. ACD/IntelliXtract software for LC/MS componentization features the ability to extract chromatographic components according to specific, user-defined isotope patterns such as radiolabels. Other MS tools have the capability to predict negative ion fragmentation and feature new file formats for LC/MS data importation. Significant changes have been made to ACD/1D NMR Manager and 1D NMR Processor to help improve structure verification workflow. ACD/1D NMR Assistant, designed for chemists, features multiplet analysis and a structure verification algorithm to bring NMR expertise to the desktop.
