Chaos and dynamics on 0.5-300 ps time scales in vibrationally excited acetylene: Fourier transform of stimulated-emission pumping spectrum

Résumé

A recently proposed technique based on the Fourier transform of the spectrum is applied to the stimulated-emission pumping spectrum of acetylene at ~26 500 cm-1 above the vibrational ground state. Correlations on two different time scales (~3 and ~45 ps) were found from analysis of low-resolution (0.3 cm-1) and high-resolution (0.05 cm-1) spectra, respectively. Additional structure produced dynamic information on a wider (0.5-300 ps) time scale. The results show that acetylene at 26 500 cm-1 is in the transition from the regular to the chaotic regime.
