A model is proposed which leads to intermediate structure in isospin-forbidden reactions. It is shown that the effects predicted by the model occur in the recent data of Jolivette for ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}(d, {\alpha }_1){}_{}{}^{14}{}_{}{}^{}\mathrm{N}\mathrm{}\left(2.31\right)\mathrm{}$.
