We theoretically propose a new control scheme of temporal wave-packet separation for oriented molecules, based on nonresonant dynamic Stark effect (DSE) in the dipole limit. In the scheme linearly-polarized single-cycle THz pulses are employed as control fields. In this work the proposed scheme is applied to the temporal wave-packet separation of the binary mixture of alkali halide isotopologues, $$^{133}$$CsI and $$^{135}$$CsI. We assume that before applying the control pulse one of the isotopologues is oriented along the field polarization direction and the other along the opposite direction and then they are electronically excited from the ground-state PEC to the excited-state counterpart. Numerical wave-packet propagations reveal that a THz pulse yields a temporal wave-packet separation of about 2 ps between the two isotopologue photodissociations.
