Rotational structures of long-range diatomic molecules

Determination of e ω , e e x ω , e B , and e α using potential energy functions for heteronuclear diatomic molecules via spreadsheet program

In order to represent the potential energy function over the whole range of R, many potentialenergy functions have been proposed. In the present paper, we employ many potential energyfunctions, to use Numerov method for solving the nuclear Schrödinger equation for the IFmolecule, as an example of a heteronuclear diatomic molecules. Then we determine thespectroscopic constants eω , e e x ω , e B...

Rotational Spectroscopy of Diatomic Molecules

The visualization of collision process of diatomic molecules

The collison of N2 molecules in which only rotation of molecules is regarded as internal degree of freedom is simulated and the energy transfer between translational and rotational energy is investigated numerically at low temperature. The results are visualized and it is shown that energy transfer changes by the direction and orientation of rotational vector and the impact parameter and it is ...

Diatomic Molecular Spectroscopy with Standard and Anomalous Commutators

In this review, we address computation of diatomic molecular spectra. An overview of the theory is discussed based on symmetries of the diatomic molecule. The standard quantum theory of angular momentum fully accounts for the rotational states of the diatomic molecule. Details are elaborated in view of standard versus anomalous commutators for generation of a synthetic spectrum. Specific exampl...

Rotational cooling of molecules using lamps

We investigate theoretically the application of tailored incoherent far-infrared fields in combination with laser excitation of a single rovibrational transition for rotational cooling of translationally cold polar diatomic molecules. The cooling schemes are effective on a timescale shorter than typical unperturbed trapping times in ion traps and comparable to obtainable confinement times of ne...
