✦ Synopsis

Electron

impact cscitntion spectra of the six fluorine-substituted ethylenes have been measured at impact energies of 20 cV or 25 CV nnd 40 CV and scattering angles from 0 ' io 80". Each of these molecules shows an absorption maximum betwccn 4.2 cV and 4.7 cV corresponding to J singlet-triplet, rr-pi* transition.

In addition, a weak absorption nt 6.45 eV seen only in monolluoroethylene is assigned to the second singlet-triplet transition. Several absorption features nt energies above the first ionization potential have also been observed in each molecule.

The Compton profile of methane is measured at 4.28 and 10 degrees using high energy electron impact spectroscopy with 25 keV electrons. The 10 degree profile is found to agree with theoretical calculations through q = 5 au. Both esperimental Compton profiles and the best available theoretical profil
