Reaction-Path-Specific Wavepacket Dynamics in Double ESIPT

Reaction-Path-Specific Wavepacket Dynamics in Double ESIPT [Pg.96]

For the single proton transfer, the donor-acceptor distance of only one of the two H-chelate rings has to be compressed. This is achieved by an antisymmetric bending motion. This example demonstrates that different reaction channels result in different coherent wavepacket dynamics. BP(OH)2 exhibits inversion symmetry, and direct optical excitation of the antisymmetric bending mode is not possible because of selection rules for electronic dipole transitions [74]. This proves that the observed coherent wavepacket motions result from ultrafast intramolecular reactions. [Pg.97]
