Abstract:	A value for the η-η' mixing angle is extracted from the data on V P γ transitions using simple quark-model ideas. The set of data covers all possible radiative transitions between the pseudoscalar and vector meson nonets. Two main ingredients of the model are the introduction of flavour-dependent overlaps for the various qq¯wave functions and the use of the quark-flavour basis to describe the η-η' system. In this basis the mixing angle is found to be φP = (37. 7 ± 2. 4)◦.
