Quantum optimal control of isotope-selective rovibrational excitation of diatomic molecules

Kurosaki, Yuzuru*; Yokoyama, Keiichi  

Electric field of laser pulses is designed by the optimal control theory. The target process is isotope-selective rovibrational excitation of two isotopologues of the lithium chloride molecule, LiCl or LiCl. The calculation includes both radial and angular motion of atoms in molecule. As a result, it is found that a laser pulse field which can cause isotope-selective rovibrational excitation with high yield exists.
