Analysis of excitement and fluorescence spectra of Cs_2 33∑+g, a3∑+u and Rb_2 23ПOg, a3∑+u states
Skublov Aleksei 

Cesium and rubidium dimers play an important role in various fundamental and applied research. All applications require accurate knowledge of the electronic structure of the molecule and its inter-atomic potential energy functions both in singlet and triplet states. 
In current work excitement and fluorescence spectra of Cs2 and Rb2 obtained via Perturbation Facilitated Optical– Optical Double Resonance (PFOODR) technique were analyzed. The primary aim was to obtain information about molecule structure by analysis of experimental data. Within the framework of the aim following tasks were set - to find the rotational and vibrational quantum numbers of observed rovibrational states and to find molecular constants of   corresponding electronic states. 
Cs2 33∑+g, Rb2 23П0g and Rb2 a3∑+u were assigned. Molecular constants (the depth of the potential well, the equilibrium interatomic separation, the equilibrium rotational constant and the principal vibrational frequency) of Cs2 33∑+g and Rb2 a3∑+u states were detemined. Potential energy function of Cs2 33∑+g, Rb2 23П0g and Rb2 a3∑+u states were constructed. Reproduction of constructed model was estimated.
