Can Quantized Vibrational Effects be Obtained from Ehrenfest Mixed Quantum-Classical Dynamics?

An interesting question is whether or not mean-field or “Ehrenfest” mixed quantum-classical dynamics can capture the quantized vibrational features in photoabsorption spectra that result from infrared and Raman-active vibrational transitions. We show that vibrational and electronic absorption spectra can be obtained together within a single Ehrenfest simulation. The electronic transitions show new sidebands that are […]
