NPNMR is a software for processing and assigning NMR (Nuclear Magnetic Resonance) spectra. NPNMR was originally designed to help natural product chemists in processing and assigning their NMR data. It offers data processing, visualization, analysis and graphics output. Its archive system uses the well accepted JCAMP-DX and -CS formats for stable long term storage of data and results. It can load data from the major spectrometer vendors without manual conversion procedures. It concentrates on the daily tasks of chemists who want their work done. The program is ideal for offline processing and assignment.

NPNMR can be run on the following operation systems:

  • Microsoft Windows XP, Vista, Windows 7, Windows 8, 32bit or 64bit versions
  • Mac OS X (Lion, Mountain Lion, Mavericks, Yosemite, El Capitan) 64bit version required
  • Linux (eg. Ubuntu 10-12) 32 bit or 64 bit version
  • ARM / Raspberry PI (Raspbian) 32 bit version required
