Abstract

The vibrational state of a polyatomic molecule excited with a transform limited light pulse is determined analytically. We analyze how the properties of the vibrational state depend on the duration of the exciting pulse and the possible geometrical configurations of the nuclear potential surfaces. It is pointed out that a finite exciting pulse results in an entangled vibrational state. The magnitude of the entanglement is described by the von Neumann entropy associated with the vibrational modes. It is shown that in the case of a very short excitation, the change of the geometrical configuration of the vibrionic potential surface may also lead to entanglement.
