Experimental Windowed Fourier Transform of the Vibrational Spectrum of CS2
Abstract
We present the windowed Fourier transform or vibrogram of 960 experimental vibrational levels of CS2 up to 19 150 cm-1. The averaged vibrogram shows the evolution of the correlation hole. Then the dynamics at short times is investigated by the periodic orbit theory. The first recurrences of the vibrogram are assigned in terms of winding numbers of an integrable 3D resonance model.
