ACD/1D NMR Assistant

NMR software for synthetic chemists.

ACD/1D NMR Assistant was designed specifically with the chemist in mind. While it includes all of ACD/Labs’ powerful processing features and prediction algorithms for 1D NMR, the interface is simple and offers the functionality and capabilities most suited to a routine non-expert user. You can choose to manually or automatically process and analyze NMR data, and have the software verify your assigned structure-with 1H and 13C NMR predictors running in the background, you will receive a match factor between your experimental spectrum and the predicted spectrum for the proposed structure.

Features

  • Fully process NMR data from all major vendor formats, for 1D 1H, 13C, 15N, 19F, and 31P
  • Assignment assistance—with Multiplet Assignment Preview (MAP) for 1H spectra, hover over a multiplet and get real-time feedback on which atoms should be assigned to it
  • Automatic creation of multiplet reports
  • Assistance in structure verification (for 1H)—automatically confirm whether your proposed structure is consistent with the data, with the option to auto assign for quicker reporting
  • Macro capabilities including templates and macro organizer for completely automated data processing and analysis

Benefits

  • Process NMR data and manipulate spectra at the chemist’s desktop, remote from the instrument
  • Save time on reports, patents, and publications with automatic creation of multiplet reports in standard journal/custom formats
  • An affordable way to provide a complete NMR software package to chemists
