We examine possible assignments for known mesons to the predicted ground-state q bar q multiplets in the U~(12)SF-classification scheme of hadrons, based on their observed properties. The masses of missing members of the ground-state multiplets are estimated, using a phenomenological mixing scheme for the normal- and extra-spin wave functions specific to this classification scheme. We also examine experimental candidates for the excited 1P, 1D and 2S multiplets in a framework of the U~(12)SF X O(3,1)L-classification scheme, based on the analysis of the ground-state masses. Then we see that the two exotic mesons pi1(1400) and pi1(1600) with JPC=1-+ have suitable masses to be assigned to the P-wave excitation and also there are a number of observed mesonic states which could be classified in terms of the U~(12)SF X O(3,1)L scheme.
