The phonon spectra of YBa₂Cu₄O₈ polycrystalline samples with different isotope substitution for Ba, Cu, and O have been studied using far-infrared ellipsometry and Raman scattering. The observed isotope shifts of Raman- and infrared-active phonons provide insight into their relative Ba, Cu, and O normal mode content. This allows us to examine mode eigenvectors obtained from lattice dynamical calculations using ab initio electronic structures based on the full potential linear muffin-tin-orbital within the local density approximation. Our Raman results demonstrate that the 104 cm⁻¹ Ag
