For selected examples of diatomic molecules chemisorbed on transition and noble metals [ N 2 on Ru(001) and Ni(111), CO on Ru(001) and Cu(111)], we survey core-induced bond breaking by N1s and O1s excitation. We demonstrate that supplementary information on the primarily excited electronic states and on the mechanism of bond dissociation is supplied by ions, neutral molecules and atoms, and decay electrons emitted upon electronic evolution. By comparing yields of neutrals and ions, and their translational energies as a function of excitation energy for the different systems, we discriminate between molecular and surface-induced aspects of bond dissociation. In particular we analyze the potential of the substrate–adsorbate interaction to enhance atom selectivity in core-excitation-induced bond breaking.

Rotational Energy

Expressions are derived for the rotational energy levels of diatomic molecules in 4Σ states. These expressions contain two rho-type doubling parameters (γ's), and thus differ from earlier expressions which contain only one such parameter. The new expressions are in better agreement with the experimental data, though some discrepancy still exists.

Van Vleck's RAM method is used for calculating rotational line strengths in electric dipole transitions between electronic states of diatomic molecules arising from coupling cases which involve the nuclear spin.

The A1Π – X1Σ+ and B1Σ+ – X1Σ+ transitions of copper monobromide, CuBr, were recorded with a Fourier transform spectrometer. The emission was generated by using a hollow cathode discharge of Ar buffer gas and a mixture of Cu and CuBr powders. The mass-dependent Dunham expansion formula was used to obtain improved molecular constants for the ground, A and B states. These molecular constants provided RKR potential curves and Franck–Condon factors for the A–X and B–X transitions.PACS No. 35.80 transitions. PACS No. 35.80
