概要 | A sequential stimulated Raman adiabatic passage (STIRAP) approach is applied to the laser control of internal double proton transfer of a porphyrin derivative. The potential energy surfaces describing the motion of the two protons are evaluated from the density functional theory (DFT) calculation; the minimum-energy conformers obtained are classified as the trans- and cis-forms. It is shown that the STIRAP pulse sequence induces the transition from the most stable trans-form to the other trans-form via the cis-intermediate state on the picosecond time scale. The influence of laser intensity on the STIRAP process of the double proton transfer is discussed. (c) 2005 Wiley Periodicals, Inc. |
