Potential energy, distortion from vibronic interaction

Figure 6. Schematic representation the potential energy distortion resulting from the vibronic interaction between two close-lying excited states. The dashed curves represent the potential energy curves in the absence of vibronic coupling. (From ref. [21] with permission.)... Figure 6.

Fig. 1 The adiabatic potential surface of an electronic Eg state due to the linear vibronic interaction with a vibrational mode top) the mexican hat-shaped curve on the left is modified by higher order coupling terms, yielding a three minima-refinement, which is shown in a cross section perpendicular to the energy axes on the right. The potential surface, resulting from Tg Eg coupling (amidst), leads to an analogous three-well-structure already in first order - each of these corresponding to a tetragonal polyhedron distortion along one of the three molecular axes. The vibrational ai and e modes are shown on the bottom (adopted from [2])...
