Vnmr

vnmr is software for controlling nuclear magnetic resonance spectrometers. It is produced by Varian, Inc.

The software runs on SPARC machines with Solaris. It is composed of a command line interpreter window, an output window, and a status window.

The successor of vnmr is called vnmrJ.

Buttons

There are a number of buttons to perform specific tasks.

  • Acqi gives access to other menus :
    • insertion of the sample in the NMR machine
    • setting up of the lock
    • setting up of the shims

Command line interpreter

Main commands:

  • jexp1 : join experiment 1
  • go : start an acquisition
  • wft : Weighted Fourier Transform
  • svf : save file, saved files get a ".fid" extension
  • lf : list files
  • movetof : move time offset
  • pwd : show current directory
  • res : give resolution values of a peak
  • abc : automatic baseline correction

Beginning with "d" are a number of commands for displaying things:

  • dscale : display scale bar
  • dg: display parameters
  • dpf: display peak frequency
  • dpir: display peak integrals
  • ...

Integration :

  • ins =, integration surface (ins=100 for percentage, ins=9 for an integration on 9 protons)
  • dpirn = display partial integral normalized
