The spectrum of Zr III has been observed in the chemically peculiar B-type star Chi Lupi with the Goddard high-resolution spectrograph on the Hubble space telescope. Oscillator strengths for the dipole-allowed fine-structure transitions in Zr III between the levels belonging to the 4d2 and 4dnl (n = 4-6 and l = 1-3) configurations, which may be useful for abundance determinations, have been calculated in the LSJ-coupling scheme using the relativistic quantum-defect orbital method, with and without explicit account for core-valence correlation. For some of the studied fine-structure transitions the presently calculated f-values are the only ones available in the literature.
