We present a description of the symmetry-based method for the construction of the adiabatic potential of a symmetric molecule near the charged semiconductor surface. For this purpose, a transformation of the adiabatic potential of a free high symmetric molecule (D-3d) in the presence of uniform electric field is investigated.
The obtained adiabatic potential is analyzed with respect to the stability of molecule in the vicinity of charged surface, as a dependence of its orientation in the electric field.
