In an attempt to better resolve energetically close-lying transitions in cisfac-[3] 3+ , we measured its magnetic circular dichroism (MCD) at 1.8 K and 5 T (Figure ). The spectrum was deconvoluted with Gaussian curves yielding seven components (Figure , Table ) revealing a fine-structure of the 4 LMCT band at 450 nm. The simulated MCD spectrum obtained from CASSCF(7,7)-NEVPT2 calculations did not match the experiment (Figure ), likely because the metal-centered 4 A2 4 T2 transitions are hidden under MCD bands originating from CT states.
