abstract = {New coordination complexes of 3d metals that possess
photoactive metal-centered (MC) excited states arepromising
targets for optical applications and photocatalysis.
Ultrafast spectroscopy plays an important rolein elucidating
the photophysical mechanisms that underlie photochemical
activity. However, it can bedifficult to assign transient
signals to specific electronic excited states and
mechanistic information isoften inferred from kinetics. Here
it is demonstrated that 3d L-edge X-ray absorption
spectroscopy ishighly selective for MC excited states. This
is accomplished by probing the 2E spin-flip excited state
inCr(acac)3 using synchrotron-based picosecond time-resolved
XAS in solution. This excited state of Cr(III )has the
property that its potential is nested with the ground state,
which allows for the assessment ofpurely electronic changes
upon excited state formation. Combining the measurements
with ligand fieldand ab initio theory shows that the
observed spectral changes between the 4 A2 ground state and
2Eexcited state are due to an intensity redistribution among
the core-excited multiplets. Extrapolatingthese results to
higher-lying MC excited states predicts that Cr L3-edge XAS
can distinguish two statesseparated by ∼0.1 eV despite the
L3-edge resolution being limited by the 0.27 eV lifetime
width of the 2pcore-hole. This highlights the potential of
L-edge XAS as a sub-natural linewidth probe of
electronicstate identity.},
