El estudio y enseñanza de los modos vibracionales de la molécula triatómica

This work shows that by means of knowledge of the general theory of small oscillations is possible to solve analytically the vibrational modes of the triangular molecule, and from comparative results between the linear and triangular molecule can access the dynamics of the triangular molecule and simplify the analysis. To illustrate this, is modeled mechanically a triatomic molecule using the Lagrangian formulation and assuming a type of molecule in which the masses (atoms) are located at the vertices of a triangle. For an analytical treatment of the problem we use the theory of small oscillat...
