Isotope-selective rotational control based on molecular rotation is expected to serve as a preparatory step for improving the efficiency of subsequent isotope separation techniques, because it can create spatially distinct states for different isotopologues. While H₂O and T₂O are C_2v-symmetric molecules possessing a symmetry plane, they are classified as asymmetric-top molecules. Although nonresonant laser pulses are commonly used to control the rotation of asymmetric-top molecules, the favorable conditions, such as polarization schemes and pulse intervals, have not yet been fully clarified. In this study, numerical simulations of molecular rotation are performed to investigate the extent to which isotope-selective rotational control can be achieved and to identify the experimental conditions required for its realization.
