Abstract

Resonance Raman spectra including absolute resonance Raman cross section measurements have been recorded for four excitation wavelengths within the A-band ligand to metal charge transfer (LMCT) absorption at ˜ 340 nm of trans-dichlorobis(triphenylphosphine) palladium (II). A relatively simple model together with time-dependent wavepacket calculations were used to simulate simultaneously the absolute absorption and resonance Raman intensities in order to get an estimate of the vibrational reorganizational energies associated with the Aband absorption plus the homogeneous and inhomogeneous broadening to the absorption bandwidth. It seems that there is significant interaction of the triphenylphosphine ligands with the Cl/Pd chromophore of the LMCT absorption band. The results for transdichlorobis(triphenylphosphine) palladium(II) are compared with those of other inorganic compounds.
