Abstract
Laboratory spectra of the oxygen $A$-band ($b$$^{1}\Sigma ^{+}_{g} \leftarrow X^{3}\Sigma ^{-}_{g}$) have been recorded using frequency-stabilized cavity ring-down spectroscopy (FS-CRDS) in the 12,900-13,080 cm$^{-1}$ spectral region (20$<$$N$$^{\prime \prime}$$<$40). High-resolution and high-sensitivity measurements of line shape parameters (intensities, pressure broadening and shifting) are reported. Implication of line-mixing and collision-induced absorption to far-wing absorption will be discussed.
