Probing weakly bound molecules with nonresonant light.

We show that weakly bound molecules can be probed by "shaking" in a pulsed nonresonant laser field. The field introduces a centrifugal term which expels the highest vibrational level from the potential that binds it. Our 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.

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.

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.
