Masses and topological charges of the {eta} and {eta}{sup '} mesons are expressed in terms of the singlet-octet mixing angle {theta}. Contributions of the pseudoscalar 0{sup -} continuum are evaluated in a model independent way. Applications to the decay {eta}{yields}3{pi} and to the radiative decay of vector mesons involving {eta} and {eta}{sup '} are considered. Agreement with experiment is, in general, good and the results quite stable for -30.5 deg. < or approx. {theta} < or approx. -18.5 deg.
