Abstract (from CDS):

Precision laboratory measurements are presented for 135 O I lines in the infrared (including 51 lines not measured previously in the laboratory) using time-resolved Fourier transform infrared spectroscopy in the 800-13,000 cm–1 region. The fine structure of some lines is observed for the first time. Using our linelist together with all relevant measurements from other works, we perform a re-optimization of O I level energies to obtain an internally consistent system of 2p3[4S]nl levels. Some O I level energies measured long ago are corrected. We also present a long list of oscillator strengths calculated with the help of quantum defect theory.
