We examine proposed mixed symmetry states in both the N=30 and N=84 isotones. In the former case the data are consistent with a mixing of the lowest mixed symmetry state with the two phonon state. This mixing can be described by a perturbation of the strict vibrational limit, due to the introduction of a quadrupole term. This analysis further suggests that no mixing should occur in52Ti, despite the states being separated by less than 200 keV. The case in the N=84 isotones is less clear due to the influence of two neutron excitations which mix and spread the mixed symmetry strength over several states.
