The manifestations of the {omega} {yields} 3{pi} contact term and its unitary partners are investigated in the framework of the chiral effective Lagrangian theory with vector mesons. We conclude that, nowadays, the existence and magnitude of the contact term can be extracted neither from theory nor from experiment. The theoretical uncertainty is caused by the one-loop corrections. Some speculations about them lead to the generalized KSRF relation. 53 refs., 5 figs., 1 tab.
