Introduction to Mass Spectrometry -- Interpretation

Here are a list of steps to follow when interpreting a mass spectrum.  This simplified list will help you to interpret many spectra, however there are other mechanisms of fragmentation which cannot be covered in this brief tutorial.

Steps to interpret a mass spectrum:

1.  Look for the molecular ion peak.

2.  Try to calculate the molecular formula: 3.  Calculate the total number of rings plus double bonds: 4.  Postulate the molecular structure consistent with abundance and m/z of fragments. RETURN TO CONTENTS
