TL;DR: In this article, a variational approach for computing the rovibrational dynamics of polyatomic molecules in the presence of external electric fields is presented, where the effect of the external electric field is treated as a multipole moment expansion truncated at the second hyperpolarizability interaction term.

TL;DR: In this article, a robust variational approach is used to investigate the sensitivity of the rotation-vibration spectrum of PH3 to a possible cosmological variation of the proton-to-electron mass ratio, μ.

TL;DR: The present method can be readily optimized for any chiral molecule with an anisotropic polarizability tensor by adjusting the polarization state and intensity profile of the laser field.

TL;DR: In this paper , the rotation-vibration-electronic (rovibronic) line lists for calcium monohydride (40Ca1H) and magnesium mg1H and its minor isotopologues were presented.

TL;DR: In this paper, the authors show that the relationship between the probed properties and their mass sensitivity can be derived from numerically exact solutions of suitable radial Schrodinger equations for a set of effective potential energy curves, and the resulting relations exhibit a weak dependence on the short-range part of the used potentials and a near-negligible dependence on higher-order nonadiabatic, relativistic, QED and residual retardation effects.
