Figure 5.
(a) Calculated (TDDFT) and experimental absorption spectrum of cis,trans,cis-[Pt(N3)2(OH)2(NH3)2] in H2O. The excited states are shown as vertical bars with heights equal to their extinction coefficients. Transitions S1–S4 have all dissociative character since they involve (b) the σ-antibonding orbitals LUMO and LUMO+1.
