Topologically nontrivial fluctuations control the anomalous interactions for the and pseudoscalar mesons. We consider the anomalous interactions for mesons with higher spin, the heterochiral nonets with and . Under the approximation of a dilute gas of instantons, the mixing angle between nonstrange and strange mesons decreases strongly as increases, and oscillates in sign. Anomalous interactions also open up new, rare decay channels. For glueballs, anomalous interactions indicate that the state is primarily gluonic.
