摘要: Abstract The merits and drawbacks of a mixed quantum-classical description nuclear motion on coupled potential energy surfaces are discussed compared with fully quantal treatment. For the latter particular approach is highlighted in which an efficient wavepacket propagation scheme, Multiconfiguration Time-Dependent Hartree (MCTDH) method, combined versatile modeling Hamiltonian for interacting surfaces, linear vibronic coupling (LVC) model. As illustrative example this treatment applied to benzene radical cation, where five multiply intersecting up eleven degrees freedom has been studied. results electronic population dynamics allow understand recent pump-probe spectra ultrashort XUV visible/near IR laser pulses terms few-fs transfer at two consecutive conical intersections.
