We present the results of precise laboratory measurements of the infrared (IR) spectrum of neutral oxygen (O I) atom using the time-resolved IR Fourier transform spectroscopy technique in 800−13000 cm−1 range. Based on 135 measured lines (including 51 lines previously not observed in the laboratory) and taking into account all previous measurements of the O I spectrum, a reoptimization procedure was performed, resulting in an updated system of levels internally matched to an accuracy of at least 0.01 cm−1. A large array of oscillator strengths and transition probabilities is calculated in the considered spectral range.
