Abstract
The detection of electronegative gases through the use of a dissociative electron attachment process is enhanced by exciting the molecules of an electronegative gas of interest to an electronic or vibrational level to increase the cross section of the molecule for dissociative attachment of electrons to produce negative ions indicative of the gas molecules of interest.
