Abstrakt:	Resonance Raman spectra have been obtained at four excitation wavelengths within the A-band ligand to metal charge transfer (LMCT) absorption of trans-dichloro-bis(tricyclo-hexylphosphine) palladium(II)and a resonance Raman intensity analysis was done to elucidate the excited state structure relative to the ground state. Comparison of the present results for trans-dichlorobis(tricyclohexylphosphine) palladium(II)with those previously reported for trans-dichlorobis(triphenylphosphine) palladium(II) shows that the phenyl ligand appears to primarily affect the adjacent P-C vibrational reorganizational energy and doesnot significantly perturb the Pd-Cl or Pd-P vibrational reorganizational energies.
