We obtained UV spectra with the Goddard High Resolution Spectrograph on HST. High quality data were acquired on interstellar absorption from C I and Ni II toward rho Oph, chi Oph and zeta Oph. At least one dozen lines were detected for each species. In most cases, the individual velocity components were resolved so that a curve-of-growth analysis could be performed. For C I, accurate column densities and Doppler parameters were derived from lines with precise laboratory-based f-values. These column densities and b-values were used to obtain a self-consistent set of f-values for comparision with results from large-scale atomic computations. The set of f-values were further constrained by the need to reproduce data for more than one sight line. Since no experimental results exist for the Ni II lines detected in our spectra, we could only obtain an accurate set of relative f-values.
