Title: Experimental and theoretical investigation of the Stark effect for manipulating cold molecules: Application to nitric oxide

Abstract

As part of an ongoing investigation of cold-molecule collisions involving nitric oxide (NO), we here theoretically assess the first- and second-order perturbation-theory approximations to the Stark shifts; such approximations have been used almost exclusively in previous published research on NO in external electric fields. We perform this assessment by comparison to Stark shifts from the corresponding nonperturbative two-state model, considering field strengths from zero to values typical of current experimental studies of cold molecules. To facilitate the future use of this model, we give expressions for the Stark energies in a generic form that can trivially be applied to any molecules in the class under consideration. To provide insight into the validity of the two-state model, we also experimentally assess the two-state Stark shifts for NO.
