 Title: PHOTOACOUSTIC PRESSURE BROADENING MEASUREMENTS OF TRANSITIONS IN THE $O_{2} b^{1}{\Sigma_{8}}^{+} \leftarrow X^{3}{\Sigma_{8}}^{-}$ $BANDS^{\ast}$ Creators: Bragg, S. L.; Lawton, S. A. Issue Date: 1982 Abstract: High-resolution spectra of individual rotational lines in the 0-0 and 1-0 bands of oxygen (762 and 668 nm, respectively) have been measured photoacoustically. Line strengths and pressure broadening coefficients have been determined for both self broadening and foreign-gas broadening at pressures up to 3 atm. Comparison of these measurements with previous $observations^{1, 2}$ permits the calibration of the photoacoustic detector response. The importance of the modulation frequency in the absolute calibration is discussed. URI: http://hdl.handle.net/1811/29127 Other Identifiers: 1982-FB-13
