We have calculated vertical excitation energies and oscillator strengths of the low lying electronic transitions in , , and using a hierarchy of coupled cluster response functions [coupled cluster singles (CCS), second order approximate coupled cluster singles and doubles (CC2), coupled cluster singles and doubles (CCSD), and third order approximate coupled cluster singles, doubles, and triples (CC3)] and correlation consistent basis functions (n-aug-cc-pVXZ, where and ). Our calculations indicate that significant changes in the absorption spectra of the photodissociative states of and monomers occur upon complexation. In particular, we find that the electronic transitions originating from are blueshifted, whereas the electronic transitions originating from are redshifted.
