Abstract
Self-broadened halfwidths have been determined for nearly 200 spectral lines of six different vibration-rotation bands of $^{16}O_{3}$ in the $4-14 \mu m$ region. These results were obtained from two series of room-temperature absorption spectra recorded at $0.005 cm^{-1}$ resolution using the McMath Fourier transform spectrometer at the National Solar Observatory on Kitt Peak. The halfwidth values were obtained through a nonlinear least-squares spectral fitting procedure, and the resulting self-broadening coefficients lie within the range of 0.08 to $0.12 cm^{-1}$ atm-1 at 296 K. These results are compared to previous measurements of ozone self-broadening, and the variation of the halfwidths with vibrational and rotational quantum numbers is examined.
