title: [Potential energy function of internal rotation for the molecules of (CX3)2Y type].
abstract: Studing on the molecules having M -tops of N -fold symmetries, decoupling the equation of motion for rotation and using the perturbation theory without wave function, the formula of the energies of internal rotation has been derived and the potential energy functions of internal rotation for (CH3)2O and (CF3)2CO have been determined.
