Quantum control of isotope-selective rovibrational excitation of diatomic molecules in the thermal distribution
- 70 Downloads
We propose a new method to excite the rovibrational states of diatomic molecules in the gas-phase isotope-selectively by optical pulses. The proposed method uses an optical frequency comb to excite the rotational states of the selected isotope molecules, and the second pulse to excite the vibrational states via the fundamental transitions in the P-branch. We demonstrate its applicability by computer simulations for lithium chloride (LiCl) molecules in the thermal distribution at 70 K.
