The LiRb molecule is one of the few heteronuclear alkali metal molecules (along with those containing one Fr atom), for which accurate spectroscopic information is still missing. On the other hand it is one of the most polar among the alkali molecules and is surely of interest in experiments with mixtures of cold atoms (e.g. D. DeMille, Phys. Rev. Lett. 88, 067901 (2002)). We report the first high resolution observation of laser-induced fluorescense in the LiRb molecule. Abundant experimental information is collected with a typical resolution of 0.03 cm−1 applying a Fourier-transform spectrometer. The present status of the analysis and preliminary potentials for the X1Σ+ ground state and the two lowest 1Π states are presented.
