By making use of the quantization rule of Raab and Friedrich [Phys. Rev. A 78, 022707 (2008)], we derive simple and accurate formulae for the number of rotational states supported by a weakly bound vibrational level of a diatomic molecule and the rotational constants of any such levels up to the threshold, and provide a criterion for determining whether a given weakly bound vibrational level is rotationless. The results depend solely on the long-range part of the molecular potential and are…

Probing weakly bound molecules with nonresonant light.
TLDR
Numerical simulations applied to the Rb(2) and KRb Feshbach molecules indicate that shaking by feasible laser pulses can be used to accurately recover the square of the vibrational wave function and, by inversion, also the long-range part of the molecular potential.
Influence of higher-order dispersion coefficients on near-threshold bound and continuum states: application to 88Sr2.
TLDR
A general formalism is presented which is valid for weakly bound and low-energy continuum states, both for vanishing and non-vanishing angular momentum, and applicability is demonstrated for the electronic ground state of the strontium dimer.
Effect of a magnetic field on molecule-solvent angular momentum transfer.
TLDR
It is shown that exchange of angular momentum between the molecule and the solvent can be altered by the field, even though the solvent itself is non-magnetic, and a possibility to control resonant emission of phonons using a magnetic field is demonstrated.
Libration of Strongly-Oriented Polar Molecules inside a Superfluid.
TLDR
It is shown that coupling of the molecular pendular motion to the fluctuating bath leads to formation of pendulons-spherical harmonic librators dressed by a field of many-particle excitations, and that an external field allows to fine-tune the positions of these instabilities in the molecular rotational spectrum.
Pendular alignment and strong chemical binding are induced in helium dimer molecules by intense laser fields
TLDR
A theoretical study of laser interactions in two realms: fields not strong enough to dislodge electrons, but interacts with the anisotropic polarizability to induce spatial alignment of the molecular axis; and superintense, high-frequency lasers that impel electrons to undergo quiver oscillations that interact with the intrinsic Coulomb forces and induce an extremely strong chemical bond.
Exact solution of multidimensional hyper‐radial Schrödinger equation for many‐electron quantum systems
In quantum theory, solving Schrodinger equation analytically for larger atomic and molecular systems with cluster of electrons and nuclei persists to be a tortuous challenge. Here, we consider,
Manipulation of molecules with electromagnetic fields
The goal of the present article is to review the major developments that have led to the current understanding of molecule–field interactions and experimental methods for manipulating molecules with

Rotational structures of long-range diatomic molecules
Abstract.We present a systematic understanding of the rotational structure of a long-range (vibrationally highly-excited) diatomic molecule. For example, we show that depending on a quantum defect,
Dependence of the Diatomic Rotational Constant Bν on the Long-Range Internuclear Potential
A simple expression is derived which explicitly relates the rotational constant Bν for vibrational levels near the dissociation limit D of a diatomic molecule, to the nature of the long-range
Dissociation Energy and Long‐Range Potential of Diatomic Molecules from Vibrational Spacings of Higher Levels
An expression is derived which relates the distribution of vibrational levels near the dissociation limit D of a given diatomic species to the nature of the long‐range interatomic potential, in the
Quantization of the highest levels in a molecular potential
The position of the highest level in a molecular potential is not well described by the usual JWKB quantization formula. This is due to an effect which is the mirror image for bound states of the
Quantization in molecular potentials
We present a modified Bohr-Sommerfeld quantization rule for calculating energy levels in a molecular potential; it is based on the appropriate consideration of the reflection phase at the outer
Interisotope determination of ultracold rubidium interactions from three high-precision experiments.
Combining the measured binding energies of four of the most weakly bound rovibrational levels of the 87Rb2 molecule with results of two other recent high-precision experiments, we obtain
Metastable feshbach molecules in high rotational states.
TLDR
It is shown that the metastable character of Cs2 Feshbach molecules arises from the large centrifugal barrier in combination with negligible coupling to states with low rotational angular momentum, which facilitates dissociation on demand with a well-defined energy.
Analytical correction to the WKB quantization condition for the highest levels in a molecular potential
Abstract:We have recently shown that the highest vibrational level in a molecular potential is not well described by the semiclassical JWKB quantization formula and that there is a complete analogy
Improved LeRoy-Bernstein near-dissociation expansion formula, and prospect for photoassociation spectroscopy.
TLDR
Results indicate that the LeRoy-Bernstein formula could be used to improve the determination of the asymptotic coefficient and to extract relativistic correction from photoassociation spectra of long-range potential curve of diatomic molecules.
