X-ray near edge absorption spectroscopy was used to probe the electronic structure of multiferroic orthorhombic LuMnO₃ polycrystalline samples and strained, twin-free orthorhombic (1-10) LuMnO₃ films grown by pulsed laser deposition on (1-10) YAlO₃ substrates. For all o-LuMnO₃ samples X-ray near edge absorption spectroscopy spectra reveal that the pre-edge structure is influenced by the increase in MnO₆ distortion as a result of the smaller Re-ion or film strain. Furthermore there is clear evidence of anisotropic Mn-O bonding and Mn orbital ordering along the c- and [110] direction. The experimental film and bulk data are in agreement with ab initio simulations.
