The hypothesis of the single state dominance (SSD) in the calculation of the two-neutrino double beta decay (2 nu beta beta -decay) of Mo-100 is tested by an exact consideration of the energy denominators of the perturbation theory. Both transitions to the ground state as well as to the 0(+) and 2(+) excited states of the final nucleus Ru-100 are considered. We demonstrate that by experimental investigation of the single electron energy distribution and the angular correlation of the outgoing electrons, the SSD hypothesis can be confirmed or ruled out by a precise 2 nu beta beta -decay measurement (e.g. by NEMO III collaboration).
