We identify exact excitation content of the intermediate states for the one-particle Green's functions, spin-spin, and (charge) density-density correlation functions of the periodic one-dimensional t-J model with inverse-square exchange. The excitations consist of neutral S=12 spinons and spinless (charge -e holons with semionic fractional statistics and bosonic (charge +2e) "antiholons" which are excitations of the holon condensate. We find a set of selection rules and the regions of nonvanishing spectral weight in the energy-momentum space for the various correlation functions.
