Weisskopf-Wigner decay of excited oscillator states.
We investigate the analogy between exponential decay of a quantum system into a continuum, and laser-induced excitation of a molecular wave packet. We find that the analogy exists, but it is not as clear-cut for the excited vibrational states of the electronic molecular ground state, as it is for the corresponding vibrational ground state.
