Vnmr Explained
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.

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
