The extinction of Br2 molecules in gas state is measured for different wavelengths of incident light in interval of 370 – 570 nm by method of gas spectroscopy. The measurement is made on the basis of Franck-Condon’s principle, under which a transition to a more excited state is done without changing the intercore distance (in further text, R). The graph of energy dependence on extinction is drawn. On the graph are recognized two Gausses slopes and their separation (deconvolution) is done. The complete Gausses functions are determined on graph. The method of mirror symmetry is applied on Gausses slopes of extinction and symmetrical extinction values (Es) are obtained. Borders of Franck-Condon’s area are determined from ground state of Linear Harmonic Oscillator (LHO). Tables of dependence on R and the excitation energy are given. On the basis of these tables are drawn potential curves of electron energy E(R) in excited electronic states of Br2 molecules as functions of R in Franck-Condon’s area.
