Theoretical results from multi-state non-relativistic R-matrix (close-coupling) calculations are presented for electron-impact-induced transitions between excited states of molybdenum. The results are then used in modelling a low-pressure mercury-free Ar-MoO3 discharge lamp. Despite the complexity in the structure description of such an open-shell target and the resulting challenges in subsequent collision calculations, it is shown that an ab initio calculation can predict the most important kinetic pathways leading to the emission of visible and ultraviolet radiation. Satisfactory quantitative agreement, within approximately a factor of 2, is obtained between the measured and modelled spectra of the molybdenum-oxide discharge lamp.
