Up to now four different ways for obtaining ensembles of cold polar molecules are proposed and applied: photoassociation, Feshbach resonances, deceleration or selection of molecules with low translation energy by inhomogeneous electric fields and buffer gas cooling.
For a quantitative description of these processes a large amount of detailed spectroscopic data is needed which was not obtained in earlier work because its goal was concentrated on systematics of molecular structures.
We will open the view how to obtain needed molecular data for the regime of cold collisions and their resonance structure, of weakly bound systems and for transfer processes to long living states.
This should also give the base for the discussion of new applications of cold ensembles of polar molecules.
