The SU(6)_w - group structure appears in both current algebra and in the spectroscopy of hadrons. Recently, considerable progress has taken place in relating these two SU(6)_w structures. We investigate the consequences of proposed correspondence, as it applies to real photon transitions, in Part 1 of this work. We show the general structure of such transitions and present a set of resulting selection rules for the multipole character of the photon amplitudes. Many specific amplitudes for both mesons and baryons are worked out and their signs and magnitudes are compared with available experimental data.
