- Temporary negative ion states of molecules and their decay channels, particularly, dissociative electron attachment (DEA)
- Measurement of vertical attachment energies (VAE) and absolute total cross sections for DEA process. Understanding the correlations between these properties in various molecular families.
- DEA as a probe of intramolecular electron transfer.
- Exploration of correlations between VAEs and chemical rate constants for reductive processes, in particular, dehalogenation of pollutants on iron filings.
