Resonant VUV absorption in CsCl monomers and dimers—experiment and theory

Absorption spectra of CsCl molecule and dimer was measured by using time-of-flight technique in the photon energy region of 5p excitations of Cs. The experimental spectra was analyzed by means of point-charge-molecular-field model, which is based on the exact multiple expansion of electrostatic fiel...

Summary:Absorption spectra of CsCl molecule and dimer was measured by using time-of-flight technique in the photon energy region of 5p excitations of Cs. The experimental spectra was analyzed by means of point-charge-molecular-field model, which is based on the exact multiple expansion of electrostatic field induced by the ligands assumed to be point charges and use a complete set of | L S J M 〉 states in diagonalization. The calculations show strong inter-configuration mixing between the states originated from the excited 5p 55d and 5p 56s configurations. A good accordance between the measured and theoretical spectra shows that proposed calculation model provide a good base for the interpretation of the lowest excitations of the molecules with ionic bonding.
