Mass spectra and radiative decay widths for q¯ mesons taken from well-established results of the Particle Data Group are fit by the O(4)
U(3) transitional theory of the U(4) vibron model. The results are compared with those of the O(4) limit of the theory and the quark potential model. The O(4)
U(3) transitional theory seems to give a better description of the heavy q¯ mesons, while the O(4) limit gives an accurate description of the light and strange q¯ mesons.
