Photoionisierungsquerschnitte: Unterschiedliche relative Bandenintensitäten in He-I- und He-II-Photoelektronenspektren

Abstract: Arbeit bestimmte Wert von 68.8 Hz fur Jcfc2 in 1,3-Butadien liegt erwartungsgemalj in dem Bereich fiur Doppelbindungen.Wir vermuten, daR der genaue Betrag von 'JCC weiterhin von dcr Anzahl der Kohlenstoff-Substituenten an der C=C-Doppelbindung abhangt. Hierfiir spricht der Gang dieser Kopplung vom unsubstituierten Athylen uber Propylen mit 70.0[81 zum Isobuten rnit 72.6 HzL8]: pro Kohlenstoff-Substituent nimmt lJc=c um 2-3 Hz zu. In diese Reihenfolge pa& auch das Styrol rnit 'JcZc = 70 Hz[''.Auch wenn man den … Show more

“…Our particular interest in understanding photoionization cross sections arises from their value in revealing electronic structure and bonding information from the photoelectron spectra of inorganic and organometallic molecules. Some of the most useful information for assigning and interpreting ionizations of molecules has come from the comparison of spectra obtained with different photon energies, because the photoionization cross section is dependent upon the energy of the ionizing photon and the character of the molecular orbital. This information has been used since the earliest days of molecular photoelectron spectroscopy, , and variable energy photon studies have become increasingly common since the advent of high-intensity tunable synchrotron radiation sources. , The general trends that have been observed for photoionization behavior often lead to a clear and convenient differentiation between ionizations from metal-based and ligand-based orbitals in the photoelectron spectra of inorganic and organometallic molecules.…”
