摘　　要：This study shows the unexpected and counterintuitive possibility of simultaneously orienting a molecule while delocalizing its molecular axis in a plane in field-free conditions.The corresponding quantum states are characterized,and different control strategies using shaped terahertz(THz)laser pulses are proposed to reach such states at zero and nonzero temperatures.The robustness against temperature effects of a simple control procedure combining a laser and a THz pulse is shown.Such control strategies can be applied not only to linear molecules but also to symmetric top molecules.
