摘要：

We investigate photodissociation of the gas-phase palladium complex anions, Pd(II)Cl3- and Pd(I)Cl2- , both experimentally and theoretically. Visible photodissociation mass spectrometry reveals that the main dissociation channels differ for Pd(II)Cl3- and Pd(I)Cl2- ; the former yields neutral chlorine atom (Pd(I)Cl2- + Cl) whereas the latter affords chloride anion (Pd(I)Cl + Cl-). Absorption spectrum and photodissociation channels are predicted using the MRCI method. The observed absorption spectrum and dissociation product for Pd(II)Cl3- agree with the MRCI calculation, whereas those for Pd(I)Cl2- do not, which suggests that some relaxation process such as internal conversion significantly contributes to the photodissociation of Pd(I)Cl2- .
