We characterize excited state quantum phase transitions in the twodimensional limit of the vibron model with the quantum fidelity susceptibility,comparing the obtained results with the information provided by theparticipation ratio. As an application, we perform fits using a four-bodyalgebraic Hamiltonian to bending vibrational data for several molecular speciesand, using the optimized eigenvalues and eigenstates, we locate the eigenstateclosest to the barrier to linearity and determine the linear or bent characterof the different overtones.
