    "abstract": "We study the control by electromagnetic fields of molecular alignment and\norientation, in a linear, rigid rotor model. With the help of a monotonically\nconvergent algorithm, we find that the optimal field is in the microwave part\nof the spectrum and acts by resonantly exciting the rotation of the molecule\nprogressively from the ground state, i.e., by rotational ladder climbing. This\nmechanism is present not only when maximizing orientation or alignment, but\nalso when using prescribed target states that simultaneously optimize the\nefficiency of orientation/alignment and its duration. The extension of the\noptimization method to consider a finite rotational temperature is also\npresented.",
