摘要：

We report the direct observation of the orientation of jet-cooled molecules induced by a THz pulse. The intense THz field (similar to 30 kV/cm) creates a superposition between the rotational ground state (J = 0) and the excited state (J = 1) of HBr molecules. The rotational dynamics is probed by Coulomb explosion imaging of the fragment ions produced by a near-infrared femtosecond laser pulse. Comparing with the simulations based on a time-dependent Schrodinger equation, the rotational wave packets are completely reconstructed, which reveal that similar to 7 x 10(-4) of the ground-state population is transferred to the J = 1 state at an initial temperature of 8 K, achieving a degree of orientation of < cos theta > similar to 0.017.
