✦ Synopsis
Laser-induced fluorescence is combined with a variety of electron excitation techniques to study the details of the electronimpact dissociation process in water and methanol. The OH(X, v=O) rotational "temperature" was determined to be 210 and 310 K for electron-impact dissociation from water and methanol, respectively. Comparisons between this excitation scheme and previous photodissociation studies are made. It was found that there was preferential population of the OH(X) A" Adoublet level as was also observed in photodissociation studies. The shapes and relative magnitudes of the cross sections for the production of OH(X) and OH(A) via electron-impact dissociation from water and methanol have also been measured for impact energies from 100 to 400 eV.
