Abstract

Halfwidth and pressure-induced line shifts for ozone perturbed by nitrogen have been calculated using the quantum Fourier transform theory with improved dynamics (QFT-ID). All unique rotational transitions from J = 1 to 35 present on the AFGL main gas atlas (4852 transitions) have been considered. The halfwidth as a function of J, Ka, and transition type is considered for the first time over a full range of these quanta. Comparison with experiment shows the QFT-ID results for the halfwidth to be accurate to 5–10%. No corresponding measurements of the line shift have been made, hence the accuracy of the line shift is unknown; they can be used, however, for predicting trends.
