The single-crystal reflection spectra corresponding to having the Incident radiation polarized along the a, b, and c crystallographic axes of the 1:1 complex of phenazine and iodine have been obtained. These spectra, along with the absorption spectra obtained from them via Kramers-Kronig analyses, will be reported. These results will be discussed in terms of the charge-transfer transition between phenazine and iodine and the transitions localized in the donor and acceptor molecules. The assignments that are thus provided for phenazine will be discussed in terms of $\pi$-electron theory for aromatic hydrocarbons.
