Partial Ionization Cross Sections of Organic Molecules

Published

Author(s)

Karl K. Irikura

Abstract

Partial ionization cross sections are the absolute yields of specific ions from an electron- molecule collision. They are necessary for modeling plasmas and for determining the sensitivity of mass spectrometers, among other applications. One mass-spectrometric application is for estimating the abundance of organic compounds on Mars, as sampled by the rover Curiosity. This is a report of semi-theoretical data obtained for a collection of organic molecules identified as possible biomarkers in this exotic context.
