Femtosecond Coherent Dynamics of Bromine Molecules in Clathrates

We simulate the dynamics of vibrational coherence in the excited electronic states of bromine molecules enclosed in clathrate hydrates. The molecules are probed by three femtosecond pulses to induce Raman coherence among the vibrational modes of the first excited electronic level and generate Anti-Stokes signal. The theoretical results are compared with the experimental data.
