摘要: We present results from simulations of vibrational energy and phase relaxation electronic curve crossing using a multilevel formulation Redfield theory, which demonstrate the shortcomings optical Bloch approximation importance coherence transfer processes in dynamics systems. Specifically, we show that for harmonic well, can occur with retention phase, sufficiently strong coupling, product an process be formed vibrationally coherent even when no is initially excited state.
