✦ Synopsis

Quantum-mechanical calculations on a realistic system show that excitation of a local mode may be accomplished by using two lasers. More importantly, this local mode does not decay into the bath modes of the molecule even at very long times. This excitation is accomplished using two lasers tuned to two eigenstates whose wavefunctions interfere to give the local excitation. Most significantly, this observation for a model system implies that mode specific control of chemical reactions may be accomplished using two lasers to excite two overtone transitions.
