This study investigates the symmetry of nonlinear normal mode vibrations of a two-dimensional molecule. Present numerical analysis revealed that nonlinearity of the system excites higher order harmonics in the normal mode vibration. Fourier spectrum analysis revealed that vibration symmetry of the higher harmonics can be classified on the basis of magnetic point group rather than the conventional irreducible representation of point group. This result indicates that magnetic point group is the appropriate framework for classification of normal mode vibration of solids.
