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
