Abstract
Controlling the vibrational state of molecules with tailored light pulses are of special interest of today’s research in molecular physics. In this paper the vibrational state of a polyatomic molecule excited with a transform limited light pulse is calculated analytically. In a diatomic molecule the vibrational analogue of the optical Schrödinger cat state can be realized in the experiment of double pulses. In polyatomic molecules 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.
