  We discuss advantages and limitations of the spin noise spectroscopy for
characterization of interacting quantum dot systems on specific examples of
individual singly and doubly charged quantum dot molecules (QDMs). It is shown
that all the relevant parameters of the QDMs including tunneling amplitudes
with spin-conserving and spin-non-conserving interactions, decoherence rates,
Coulomb repulsions, anisotropic g-factors and the distance between the dots can
be determined by measuring properties of the spin noise power spectrum.
