CID Spectra of Selected Target Molecules

Abstract

This report describes research into the molecular dynamics of the collisionally induced dissociation (CID) process. This process occurs in tandem mass spectrometers, and is the major process by which primary or parent ions are converted into daughter ions of smaller mass. This work was undertaken in search of a means of standardizing conditions for tandem mass spectrometers so that standard spectral data bases could be collected and used to identify environmental unknowns. This research indicates that CID cross sections for the parent ions can be reproducibly measured as a function of collision energy, and are characteristic of the parent ion structures. Measurement of CID cross sections offers a new means of identifying unknown compounds.
