This is a utility developed and used in the NIST Mass Spectrometry Data Center to assist in the evaluation of mass spectra. It finds possible structural origins of peaks in a mass spectrum and provides formula and isotopic processing utilities. It can operate in conjunction with the NIST MS Search Program or standalone.
Version 3.1 replaces all earlier versions 2.0 under 32-bit and 64-bit Windows.
MS Interpreter was described in a poster in the meeting of the International Mass Spectrometry Society, Edinburgh, UK, 2003, “An Automated Method for Verifying Structure-Spectral Consistency Based on Ion Thermochemistry”

The following instructions assume that you have a earlier version of MS Interpreter installed on your PC.
The following instructions assume that you do not have a earlier version of MS Interpreter installed on your PC.
The MS Interpreter window should pop up and display the selected spectrum and (if present) the chemical structure. The Help/About box should display “MS Interpreter Version 3.1” or later.
