'The objective of this research program is to develop new plasma chemical processes for the destruction of volatile toxic compounds (VTCs) in contaminated air streams where the contamination levels are below a few percent. The authors plan to exploit the large cross sections associated with dissociative electron attachment to highly excited molecular states. Such highly excited states are to be populated in glow discharges via excitation transfer from high- lying, metastable states of rare gases. Basic knowledge of the excitation transfer processes and the electron attachment processes are crucial to the development of the proposed techniques, and these processes will be studied in detail.
