ELECTRON-ENERGY-LOSS SPECTRA OF TOLUENE AND XYLENES

The electron energy-loss spectra of toluene, o-xylene, m-xylene and p- xylene have been measured at electron energies of 50 eV and of 3 eV ab ove the threshold; the scattering angles were 23, 45 and 68-degrees at 3 eV. The spectra of the four molecules are similar. Three new bands have been observed at 3.7-3.8, 4.6 and 5.5 eV, and they are assigned a s transitions from the ground state to the first three triplet states.
