Experimental observation of nonadiabatic bifurcation dynamics at resonances in the continuum.

It is evident that IVR among S 1 /S 2 vibronic manifolds becomes quite significant at least from the S 1 internal energy of 658 cm –1 , as manifested in the diffuse featureless SEVI spectra taken via S 1 intermediate states of the internal energy equal to or higher than 658 cm –1 ( Fig. 3 ). 67 The IVR dynamics in the S 1 /S 2 coupling regime is intriguing by itself and provides invaluable information, as it results not only from the density of the S 1 vibrational states but also from the S 1 /S 2 vibronic coupling, which is strongly influenced by the energetic structure of the S 1 /S 2 conical intersection seam in multidimensional nuclear configurational space.
