We report on an accurate determination of the rotational constants of the ultracold long-range Cesium molecules in near dissociation domain. The scheme relies on a precise reference of the frequency difference in a double photoassociation spectroscopy induced by two laser beams based on an acoustic-optical modulator. The rotational constants are obtained by fitting a non-rigid rotor model into the frequency intervals of the neighboring rotational levels deduced from the reference.
