Abstract
A phenomenological analysis on various decay processes is performed using a n energy-dependent eta-eta' mixing angle scheme. Special attention is given to the electromagnetic couplings between lowest-lying vector and pseudosca lar mesons. The agreement between our predictions and the experimental valu es is remarkable, This analysis opens a connection to two-angle fits in the eta-eta' sector.
