The precise knowledge of excited states of alkali dimers is for example of importance for the formation of cold molecules by photoassociation[1] and subsequent stimulation to ro-vibrational levels of the ground state. A powerful method for gaining this information is the evaluation of laser induced fluorescence spectra dispersed by a high resolution Fourier-transform spectrometer and additionally producing rotational satellite lines by higher buffer gas pressures[2]. Because the assignment of this huge number of transitions is very time consuming and error-prone a special software for a partial automatization of this analysis was developed. The program has been successfully applied to the spectra of LiCs measured originally for the precise determination of the ground state[3]. The program and the resulting potentials for the B1Π and D1Π state of LiCs will be presented.
