In this paper we describe the pseudoparticles, holons, and spinons whose\noccupancy configurations describe the energy eigenstates of the one-dimensional\n(1D) Hubbard model in terms of rotated electrons. Rotated electrons are related\nto electrons by a mere unitary transformation such that rotated electron double\noccupation is a good quantum number. Moreover, we introduce the concepts of\nlocal pseudoparticle and effective pseudoparticle lattice. Our findings provide\nuseful information about the relation of the exotic pseudoparticles, holons,\nand spinons that diagonalize the non-perturbative many-electron problem to the\noriginal electrons. We provide an example showing how the derived local\npseudoparticle representation can be used in the evaluation of finite-energy\nfew-electron spectral function expressions.\n
