Intramolecular proton transfer controlled by laser pulses was simulated. The motion of a proton in a molecule was treated by a one-dimensional, asymmetric double-well potential. To control the motion of a proton, a pi -pulse approach, stimulated Raman adiabatic passage (STIRAP), and a chirping technique were applied to the system. In the or-pulse approach, the conditions of complete population inversion were determined for sequential and simultaneous irradiation of two laser fields. Similar population dynamics was obtained by a laser pulse sequence designed by global optimal control theory. The results obtained by using STIRAP and the single chirped laser pulse were compared with those obtained by using a pi -pulse approach. It was found that a single negatively chirped laser pulse enables fast population transfer but maintains the robustness.
