Electron-impact excitation of low-lying electronic states in CS2, OCS, and SO2
Variable angle, electron-impact energy-loss spectra of CS2, OCS, and SO2 have been obtained at incident electron energies of 25, 40, and 70 eV for CS2, and 30 and 55 eV for OCS and SO2. Singlet→triplet excitations are observed with peaks at transition energies of 3.36 eV in CS2, 4.94 eV in OCS, and...

Zusammenfassung: | Variable angle, electron-impact energy-loss spectra of CS2, OCS, and SO2 have been obtained at incident electron energies of 25, 40, and 70 eV for CS2, and 30 and 55 eV for OCS and SO2. Singlet→triplet excitations are observed with peaks at transition energies of 3.36 eV in CS2, 4.94 eV in OCS, and 3.40 eV in SO2. A feature which peaks at 3.65 eV in CS2 is observed to have singlet→triplet character. The CS2 and OCS spectra do not confirm the existence of several spin-forbidden transitions reported in solid phase ultraviolet absorption studies of these molecules. In SO2, no evidence is found of transitions to the 1 3A2 and 1 3B2 states, believed to lie near the well-known ? 3B1 state. |
