Zusammenfassung:
Dispersion curves for nitrogen molecules physisorbed on graphite in the herringbone (2√3 x √3) structure are calculated and compared to recent angular resolved photoemission spectra. The calculated splitting at Γ¯; of the 3σg derived molecular state and its disappearance at the Brillouin zone boundary is in good agreement with the observed spectrum. It is shown that the photoemission data for CO/Ag(111) can be also interpreted in terms of a herringbone structure.
