  We identify dd-excitations in the quasi-one dimensional compound
Ca$_2$Y$_2$Cu$_5$O$_{10}$ using resonant inelastic x-ray scattering. By tuning
across the Cu L$_3$-edge, we observe abrupt shifts in the dd-peak positions as
a function of incident photon energy. This observation demonstrates
orbital-specific coupling of the high-energy excited states of the system to
the low-energy degrees of freedom. A Franck-Condon treatment of
electron-lattice coupling, consistent with other measurements in this compound,
reproduces these shifts, explains the Gaussian lineshapes, and highlights
charge-orbital-lattice renormalization in the high energy d-manifold.
