Frequencies for 32 P-branch transitions of the O2 A-band (b1Σ+g ← Χ3Σ-u) were measured between 12975 and 13115 cm^−1 using the frequency-stabilized cavity ring-down spectrometer located at National Institute of Standards and Technology, Gaithersburg, MD. Absolute line positions were calibrated using the hyperfine components of 39K D1 and D2 atomic transitions yielding uncertainties <1 MHz (~3 × 10^−5 cm^−1). Spectroscopic parameters for the b1Σ+g(ν=0) state were calculated and compared with previously determined values. These new transition frequencies should serve as a convenient secondary calibration standard in the 760 nm region.
