Time-resolved Fourier spectroscopy has been applied to the observation of Rydberg O(I) and O(,2) infrared emission from a pulsed discharge at 0.1 torr. The emission of a 2.5 meter long column through the negative glow was observed with a newly designed discharge apparatus. A computer-controlled interferometer step-servo was developed to enable 100 microsecond time- and 0.12 cm('-1) spectral-resolution capabilities. The Rydberg features were enhanced with respect to those of contaminates by signal processing methods that utilized their individual temporal behavior. Line position determinations of the 7h - 5g, 7g - 5f, 5g - 4f and 6g - 4f O(I) lines have been made to an accuracy of 0.015 cm('-1). Polarization constants of the O(II) core have been deduced from this data. Nine newly observed and four previously observed line-like features have been attributed to Rydberg O(,2).
