Recurrences in the autocorrelation function governing the ultraviolet absorption spectra of O3

摘要

The approximate dipolendash;dipole autocorrelation function corresponding to UV photoabsorption in the Huggins and Hartley bands of ozone is obtained by Fourier transformation of theT=195 K data measured by Freeman, Yoshino, Esmond, and Parkinson lsqb;Planet. Space Sci.32, 239 (1984)rsqb;. Weak structure seen at vibrational resolution in the broad absorption bands, previously unassigned, is shown to correspond predominantly to 4ndash;5 small recurrent features in the autocorrelation function during the first 130 fs. These timehyphen;dependent features are each assigned to particular types of unstable periodic or nearly periodic orbits in the classical dynamics.
