Abstract : We described our theoretical advances that influenced the experimental creation of vibrationally and translationally cold polar molecules. Our analysis includes multi-channel bound states of ground and excited electronic states. We excellent agreement with the hyperfine structure observed in experimental data. In addition, we studied spin-orbit mixing in the intermediate state of the Raman transitions used in experiment. We also obtained the polarizability of the polar molecules near frequencies relevant for optical trapping with optical lattices. We then studied the electronic properties of a new class of polar molecules created from collisions of Li and alkaline-earth or rare earth atoms, such LiSr and LiYb. Finally, we calculated the isotropic and anisotropic interaction potentials between two polar molecules.
