Abstract
Molecular orientation of thermal ensemble induced by resonant tailored multi-color laser fields is investigated theoretically. The reason for the decrease of degree of orientation with the increase of temperature can be explained intuitively from the sign pattern of the matrix of the time evolution operator corresponding to first-order Magnus expansion. The effect of laser parameters on the sign pattern is discussed, and the control methods for laser parameters are provided. Finally, different molecules are compared to investigate the effect of molecular parameters on the orientation of molecules when temperature is considered.
期刊介绍：
Chemical Physics Letters has an open access mirror journal, Chemical Physics Letters: X, sharing the same aims and scope, editorial team, submission system and rigorous peer review.
Chemical Physics Letters publishes brief reports on molecules, interfaces, condensed phases, nanomaterials and nanostructures, polymers, biomolecular systems, and energy conversion and storage.
Criteria for publication are quality, urgency and impact. Further, experimental results reported in the journal have direct relevance for theory, and theoretical developments or non-routine computations relate directly to experiment. Manuscripts must satisfy these criteria and should not be minor extensions of previous work.
